You must be patient with Salat (Prayer):

وامر اهلك بالصلاة واصطبر عليها لانسألك رزقا نحن نرزقك والعاقبة للتقوى

[020:132] Bid your family to observe the ‘salat’ وامر اهلك بالصلاة, and stay steadfast upon it yourself. We do not seek sustenance from you. Indeed, We bestow sustenance. The final outcome hinges on piety.
  

‏47:22 فهل عسيتم ان توليتم ان تفسدوا في الارض وتقطعوا ارحامكم
‏47:23 اولئك الذين لعنهم الله فاصمهم واعمى ابصارهم

[047:022] If given authority توليتم in the land, you would disobey (Allah), spread mischief, and violate the family ties.
[047:023] Those are the ones Allah has cursed. He has made them go deaf, and has blinded their eyes.

See entry# 259 below regarding cutting ties with and parting with never-changing negative people.  So you must be mindful of both Holy Commands and to be honest with yourself and others when you try to balance between the two Holy Commands of Allah Almighty regarding the decisions that you make concerning the people that you deal with.  Simply be honest with Allah Almighty and with yourself, and draw the line loud and clear between you and all people; ALL people including relatives and strangers.  See also all other entries here and Noble Verses that deal with being kind and upright to all people, and also how to deal with neighbors.
  

Now be mindful also that Allah Almighty forbade cutting family ties with kin and relatives.  Also, Among the signs of the cursed people and nations is that they cut ties with their kin and relatives, i.e., upholding individualism and isolation as this is the dominant lifestyle of the Western societies:

‏47:22 فهل عسيتم ان توليتم ان تفسدوا في الارض وتقطعوا ارحامكم
‏47:23 اولئك الذين لعنهم الله فاصمهم واعمى ابصارهم

[047:022] If given authority توليتم in the land, you would disobey (Allah), spread mischief, and violate the family ties.
[047:023] Those are the ones Allah has cursed. He has made them go deaf, and has blinded their eyes.

But for those people who are never-changing and hopeless cases in negativity, whether they are relatives or strangers, Allah Almighty commands you to avoid and abandon all negative and hopeless people who won't change, and who keep turning things into negative environments and trials.  Negative energy is rejected in Islam.  There are ample Noble Verses that thoroughly cover this point in great details as shown above and in the entries cited below, but the following Noble Verse really captured my heart:

‏73:10 واصبر على مايقولون واهجرهم هجرا جميلا

[073:010] And patiently endure واصبر على what they utter, and part company واهجرهم هجرا with them in a handsome and polite manner جميلا.

Allah Almighty wants us to be patient with all people, and to part company واهجرهم هجرا , with those who are too negative and hopeless to change, in a handsome and polite manner جميلا.  In the Noble Verses in the entries cited below, Allah Almighty commands us to be an upright and shining example to all people.  We are commanded to be the best in manners.  In the entries above, you'll find ample Noble Verses that command:

Good Wisdom and Manners in Islam.  Invite people to Islam with beautiful preaching, wisdom and argue in ways that are best and friendliest.  Argue with the people of the Book in kindness except for those among them who do wrong (to Islam) (‏ولاتجادلوا اهل الكتاب الا بالتي هي احسن الا الذين ظلموا منهم).

Again, be wise.  Be a person of wisdom.  Those whom Allah Almighty give Wisdom have gained a Mighty Benefit.  Allah Almighty called it "an abundant wealth" خيرا كثيرا.

You must be mindful of both Holy Commands and to be honest with yourself and others when you try to balance between the two Holy Commands of Allah Almighty regarding the decisions that you make concerning the people that you deal with.  Simply be honest with Allah Almighty and with yourself, and draw the line loud and clear between you and all people; ALL people including relatives and strangers.  See also all other entries here and Noble Verses that deal with being kind and upright to all people, and also how to deal with neighbors.

Do not be argumentative, confrontational, aggressive, belligerent, quarrelsome, loud-mouthed, obnoxious, intolerable, insufferable.  Please find all of the entries above (57, 118, 148, 205, 238, 244, 250, 256, 258, 182, 195, 235, 70, 208, 229, 239, 245, 246, 43, 191, 192, 232, 237, 253) about the Glorious Quran prohibiting arguing, bullying, and the Quran's commands on how you must walk away from nonsensical and negative talk, and how you must always be upright and a good example for all people, and invite and guide people to the Right Path of Allah Almighty with beautiful wisdom, talk and patience, and to understand and appreciate people's backgrounds and situations.
  

[002:262] Those who spend their wealth in the path of Allah _ (provided) they do not, afterwards, inflict abuse (on the recipients of charity) by bragging and boasting about their generosity _ shall have their reward with their Lord. They shall not have any fear, nor shall they ever grieve.

[004:038] And (also) for those who flaunt (and flash), when they spend their wealth, in order to show off to the people. They do not believe in Allah or the Day of Judgment. Whoever has Shaitan as an intimate companion has indeed an evil companion!

[074:006] Do not seek worldly gains (in return) for favors done.
  

Do not allow yourself to be enslaved by any weakness.  Do not be weak in the eyes of others, nor allow others to devour you or take you for a weak or feeble person that they may want to abuse and/or enslave though domination (dominating you).

A weak Muslim is not the same as a strong Muslim.  Allah Almighty does not like the Weak and Oppressed ones who have little will, except for those who truly have no choice and no escape.  Allah Almighty also despises you if you're weak in will and live like a slave by others. Allah Almighty loves those who are strong Muslims and who are able and do make positive differences in the societies:

‏16:75 ضرب الله مثلا عبدا مملوكا لايقدر على شئ ومن رزقناه منا رزقا حسنا فهو ينفق منه سرا وجهرا هل يستوون الحمد لله بل اكثرهم لايعلمون

[016:075] God sets forth the Parable (of two men: one) a slave under the dominion of another; He has no power of any sort; and (the other) a man on whom We have bestowed goodly favours from Ourselves, and he spends thereof (freely), privately and publicly: are the two equal? هل يستوون (By no means;) praise be to God. But most of them understand not.

Allah Almighty loves the strong Muslims, and despises the weak ones unless they have no choice and can not bring themselves up:

[004:097] When angels take the souls of those who die in sin against their souls, they say: "In what (plight) Were ye?" They reply: "Weak and oppressed Were we in the earth." They say: "Was not the earth of God spacious enough for you to move yourselves away (From evil)?" Such men will find their abode in Hell,- What an evil refuge! -

[004:098] Except those who are (really) weak and oppressed - men, women, and children - who have no means in their power, nor (a guide-post) to their way.

[004:099] For these, there is hope that God will forgive: For God doth blot out (sins) and forgive again and again.

Muslims must fight tumult and evil and always stand for Justice and Truth.  See the ample entries here that give ample Noble Verses that Command standing up for Justice.  Here is an example of Noble Verses from Entry #208 below:

Do not let people take you for a light-minded fool فاستخف قومه.  Do not be one who people treat with levity, or be perceived as one with a light mind, or be treated with frivolity.

Challenge all arguments until the proof is thoroughly made clear to you.  Do not just accept arguments and assume they are truthful because they belong to certain people.  Produce your proof if you are truthful, and always ask for proof.

Be a straight and upright believer!  Do not trick people, or be a bad influence to them, or be a fitnah or a trial to them, even if they were disbelievers ربنا لاتجعلنا فتنة للذين كفروا واغفر لنا ربنا.  Do not be a deceiver and false.  Now, it's ok to look out for opportunities to advance yourself, and to be competitive.  But do not be a liar and a deceiver.  Do not be disingenuous and false.  Be upright:

ياايها الذين امنوا كونوا قوامين بالقسط شهداء لله

"Oh you who believe! Be upright قوامين, and uphold justice staunchly بالقسط. (Always) bear testimony for (the sake of) Allah شهداء لله...."

See Noble Verses: 43:54, 30:60, 2:111, 21:24, 27:64, 28:75, 46:13, 60:4-9, 10:85, 85:10, 4:135, 5:8, 30:31-32.

Also Entries #39 and #41:

Putting people through fitnah, trial and tumult, and causing chaos, or causing corruption in the society is worse than death itself.  See Noble Verses: 30:31-32, 2:191, 2:217, 10:85, 60:4-9, 59:16-17, 85:10, 8:39, 3:103.

Fight until there is no more fitnah, tumult or trial or corruption.  See Noble Verses: 8:39, 3:103, 30:31-32, 2:191, 2:217, 10:85, 60:4-9, 59:16-17, 85:10.

And several other entries and more Noble Verses.
  

1-  A work and deed that is acceptable to Allah Almighty has to be a True and sincere one:

‏2:139 قل اتحاجوننا في الله وهو ربنا وربكم ولنا اعمالنا ولكم اعمالكم ونحن له مخلصون

2-  When you repent, you must confess of your sin first and then demonstrate your repentance:

2:160 الا الذين تابوا واصلحوا وبينوا فاولئك اتوب عليهم وانا التواب الرحيم

9:102 واخرون اعترفوا بذنوبهم خلطوا عملا صالحا واخر سيئا عسى الله ان يتوب عليهم ان الله غفور رحيم

3-  Repent shortly after.  Repentance must happen in a short time after the sin:

4:17 انما التوبة على الله للذين يعملون السوء بجهالة ثم يتوبون من قريب فاولئك يتوب الله عليهم وكان الله عليما حكيما

4:18 وليست التوبة للذين يعملون السيئات حتى اذا حضر احدهم الموت قال اني تبت الان ولاالذين يموتون وهم كفار اولئك اعتدنا لهم عذابا اليما

[004:018]  Of no effect is the repentance of those who continue to do evil وليست التوبة للذين يعملون السيئات, until death faces one of them, and he says, "Now have I repented indeed;" nor of those who die rejecting Faith: for them have We prepared a punishment most grievous.

So to say that I'll just go to Hajj or Umrah to Mecca next year and clean the sins, or I'll just repent later, this kind of thinking is evil, and your work is worthless.  Allah Almighty will sink your deeds to nothingness (i.e., your time, money and efforts put into your false repentance will not be accepted).  See Noble Verses 18:103, 25:23, 2:167, 2:217, 3:22, 5:53, 7:147, 8:48, 9:17, 9:69, 14:18, 47:8 and many others about false "good" deeds that are totally worthless and rejected by Allah Almighty حبطت اعمالهم and هباء منثورا because they were false.  Your repentance will not be accepted by Allah Almighty.

To all Muslims, if you are one of those scammed idiots who think that if you go to Hajj or Pray one day in Mecca then all of your sins' weight will be either erased or overpowered by the heavier weight of the good deeds (a prayer in Mecca is like 1000000000000000000000000 times the regular prayers elsewhere pile of lies), then I give you the glad tidings that you're heading straight to Hell.  And you will be barking in the Day of Judgment that you were from the weak ones and scammed ones. But it will be rejected from you. See Noble Verses 14:021, 34:31-33, 40:47:

[040:047] And (imagine) when they would argue with each other in the hellfire. The weak (in this life) would say to those who deemed themselves important, “We followed you, because we were under your dominion and control. Are you now able to help us avoid some (of the pain and suffering) of the fire?”

4-  Must repent and amend:

5:39 فمن تاب من بعد ظلمه واصلح فان الله يتوب عليه ان الله غفور رحيم

5-  False repentance is for the hypocrites:

33:24 ليجزي الله الصادقين بصدقهم ويعذب المنافقين ان شاء او يتوب عليهم ان الله كان غفورا رحيما

6-  In a capsule, do not be disingenuous and false.

7-  However, do not just scandalize yourself or others to anyone and everyone without it being necessary:

‏4:148 لايحب الله الجهر بالسوء من القول الا من ظلم وكان الله سميعا عليما

[004:148] God loveth not that evil should be noised abroad in public speech, except where injustice hath been done; for God is He who heareth and knoweth all things.

Allah Almighty does not like us to boast about wrong doings and/or scandalizing ourselves or others, except when it comes to amending and fixing and repenting. There you would need to make it known that you have wronged the people you have wronged and that you are taking full responsibility and that you are working on fixing.

So for example, if I committed zina (fornication) in the past, Allah Almighty does not like me to scandalize myself about it.  If I already repented and ceased doing the sin, and it's been dead for many years, then no need to resurrect it unnecessarily to anyone and everyone.  Same thing if you learn something similar about your neighbor or anyone.  No need for libel.  You wouldn't need to know for example if I did. I wouldn't be required to tell you. However, if I want to marry a woman and she wants to know about my past, then I would required to tell her, because that would now involve marriage and a commitment from both sides.  The same goes if I hold a position for example that would require for this information to be known.

If I sin, and my sin caused harm to others, such as lying at work that caused someone to get fired or get demoted while it wasn't their fault, then I am required to speak up openly, repent and amend, and pay up for damages.  Otherwise, my repentance will not be accepted by Allah Almighty.  The Glorious Quran makes this condition very clear in the Noble Verses above.

Do not ever think about covering up for anyone.  The Noble Verses above make it abundantly clear that Allah Almighty's Wrath will be upon you.

  
Simply put:

To simply put it:  Personal sins that are limited to just you, such as watching pornography for example, are not needed to be scandalized to the public or others if you're able to cease and repent on your own to Allah Almighty.  But sins that harm others and cause injustice and damage, those MUST be exposed to the public.  You must also know that in any and all cases, all sins must be sincerely resisted, fought and ceased by the Muslim with sincere repentance to Allah Almighty, and the Muslim must step up and amend and fix any and all damages caused to others, and to seek help.  Otherwise, Allah Almighty never accepts repentance from the false ones.

Repentance in the Quran requires you to mend and to confess and to make it public and known that you have done wrong and have confessed and amended and paid back what is due to others, and that you have changed, and that you are not going back ever to the sin again.
  

Anything and everything which you do that becomes compulsive to you, dominates you, and becomes addictive to a point where you become glued to it and can't get yourself out of it is considered an addiction.  Allah Almighty defines it beautifully in the Glorious Quran as things satan uses to ويصدكم عن ذكر الله وعن الصلاة  "hinder you يصدكم from the remembrance of God, and from prayer" (The Noble Quran, 5:90-91).

So if you are unable to maintain remembrance of Allah Almighty and you are unable to perform your daily prayers due to evil compulsive and excessive things that you may have subjected and surrendered yourself to such as video games, porn, gambling, alcohol, etc..., then you suffer addiction.

To be addicted to anything evil or negative is forbidden in the Glorious Quran, and one must fight it off with all of his will, passion and power.  You must have a strong will:

You must "muster the means" (4:98) to fight your weaknesses.

"eschew such (abomination)" (5:90) and "will ye not then abstain?" (5:91) فهل انتم منتهون.

[004:097] The angels, when they took the souls of those who had been unjust to their own weal, demanded, "What hath been your state?" They said, "We were the weak ones of the earth." They replied, "Was not God's earth broad enough for you to flee away in?" These! their home shall be Hell, and evil the passage to it -

[003:139] Do not weaken and do not grieve. You will come up on top, if you are the believers.

[004:075] What is wrong with you? Why would you not fight for the sake of Allah on behalf of the weak and oppressed men, women and children? Those who pray (to Allah), “Our Lord! Rescue us from this town; its residents are cruel. Raise, by Your grace, an ally for us. Grant us by Your will a helper!”

You must not succumb, retire or surrender yourself to any evil.  Also, always fight the good fight; fight for the oppressed and fight injustice so no more tumult remains.  Yes, you can't always be victorious, but you must not ever given in or give up to evil, and you must always keep the good fight for Allah Almighty's sake in you at all time, and always put your trust and faith in Allah Almighty.  This is what Islam calls doing Jihad against yourself, which includes defeating and overcoming your weaknesses and temptations.  Do not allow yourself to ever become and addict.  The following is from Entry #50 above:

All intoxicants including alcohol and drugs, and Gambling, divination, and sorcery, and all abominations are evil.  The same Noble Word for avoiding them was also used for idols false talk or speech, lying and false testimony (فاجتنبوا الرجس من الاوثان واجتنبوا قول الزور).

Allah Almighty said: "O ye who believe! Intoxicants and gambling, (dedication of) stones, and (divination by) arrows, are an abomination,- of Satan's handwork: eschew such (abomination), that ye may prosper.  Satan's plan is (but) to excite enmity and hatred between you, with intoxicants and gambling, and hinder you from the remembrance of God, and from prayer: will ye not then abstain? انما يريد الشيطان ان يوقع بينكم العداوة والبغضاء في الخمر والميسر ويصدكم عن ذكر الله وعن الصلاة فهل انتم منتهون   (The Noble Quran, 5:90-91)"

Eschew all abominations.  And will you not abstain from all abominations?  The abominations include all intoxicants, gambling and all harmful things.

Also, Gambling and alcohol are some of satan's tools to create enmity, hatred and disunity among the Believers, and to stop the Believers from remembering Allah Almighty and from Praying.  "Satan's plan is (but) to excite enmity and hatred between you, with intoxicants and gambling, and hinder you from the remembrance of God, and from prayer: will ye not then abstain?" (5:91) انما يريد الشيطان ان يوقع بينكم العداوة والبغضاء في الخمر والميسر ويصدكم عن ذكر الله وعن الصلاة فهل انتم منتهون

Allah Almighty calls unto all Muslims TO STOP all gambling and all intoxicants consumption: "eschew such (abomination)" and "will ye not then abstain?" فهل انتم منتهون.

Allah Almighty's Forgiveness and Mercy are always there for the weak.  But you must be genuine and not false:

[004:098] Except for the men, women and children who are weak and oppressed! They are unable to muster the means (to migrate), and (therefore) find no way out.

[004:099] Perhaps, Allah will grant forgiveness to those (weak) ones. Allah is oft-Pardoning, and the most Forgiving!

You must "muster the means" (4:98) to fight your weaknesses.  Do not be false and easy target and prey for satan.  You can also fight addiction with fasting and praying to Allah Almighty, because they both strengthen your self-restraint:

[002:183] O ye who believe! Fasting is prescribed to you as it was prescribed to those before you, that ye may (learn) self-restraint,-

[029:045] Recite what has been revealed to thee of the Book; and be steadfast in prayer; verily, prayer forbids sin and wrong; and surely the mention of God is greater; for God knows what ye do.

Always stay away from temptations that lead to evil and addiction رجس من عمل الشيطان فاجتنبوه:

[005:090] O ye who believe! Intoxicants and gambling, (dedication of) stones, and (divination by) arrows, are an abomination,- of Satan's handwork: eschew such (abomination)  رجس من عمل الشيطان فاجتنبوه, that ye may prosper.
 

34:18 We placed between them and between the towns that We blessed, towns that were easy to see; and We measured the journey between them: "Travel in them by night and day in complete security."

34:19 But they said, "Our Lord, make the measure between our journeys longer," and they wronged themselves. So We made them a thing of the past, and We scattered them into small groups. In this are signs for every person who is patient, thankful.

I got this entry from a Muslim brother who added it here.  May Allah Almighty always be pleased with him.  Ameen.
