one of christian friend show me this two verses (zechariah 3:9 and zechariah 13:7) from their bible and told me look bible has prophesied that Christ must die for the sins of humanity. 

zechariah 3:9 mentioned about particular land
and zechariah13:7  mentioned about shepherd and sheep from that particular land.   it does not refer to humanity.  by their logic about salvation, thus such salvation only happen to the sheep of that particular land.

Now some others let's say, are talking about the Conquests that time as a proof to the claim that Shariah is to be spread through the sword . So how do you reply to such claims ? Why did the Prophet conquer ?

first the basis of spilling blood. we know even before the creation of humans, sayings of angels mentioned about killing and bloodshed wars among humans. This is nature of human when conflict of interest arose between them, so they end up with killings and wars.

conflict of interest that may led to bloodshed even among muslims can be due to choosing political figures governing state, dispute of sovereignty of lands.

reason to war is to counter the hostility made by enemies. if enemies choose peace, then there should not be any reason to war.

that is the point , and the prophet promised of the conquest of Qustantiniyya in Turkey( Not sure about the English correct spelling ) . So how will they be "opened " or "conquered " ( Fath ) ? And HOW will the promised Caliphate return if our enemies are still killing Muslims every where ? ?

if muslims are being killed, thus if they do not have any means to defend and retaliate. they should leave the transgressors until they possess the means to reclaim back what was theirs. But if the transgressors are among muslims, thus mightier third party should jump in to initiate peace between them.

about prophecies of conquest, it is certainly due to enemies engaging in wars and hostile towards those who spread the religion of God. and if they seize to be hostile, so does Muslim need to stop to be hostile and seek peace.

sharia being implemented by swords,
prophet s.a.w sent out his companions to preach about one God to many regions without troops. Only once Islam grew in those regions, and if those that dislike the growth of Muslimeens began to be murdering Muslims and thus retaliation is needed by means of war too.

maybe stars , trees relate or as intro to following verses. Allahu'alam.

And the heaven He raised and imposed the balance 55:7
And the earth He laid [out] for the creatures 55:10

they said 'messiah' and further emphasize some more by saying the phrase 'messenger of Allah'.
As chosen children of God, The jews believe in a quick punishing fire to wash their sin something like a 1 day hell. So thats why they have no problem killing prophets.

And [for] their saying, "Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah

He said: The need for the New Testament was decreed before Jesus was even incarnated, ...
for example see the two promise made by God in Jeremiah 33:14-26 and Jeremiah 31::31-37

..... Jeremiah 33:26 For I will restore their fortunes and will have mercy on them.

Jeremiah 31:31 “The days are coming,” declares the Lord,    “when I will make a new covenant with the people of Israel    and with the people of Judah.
Jeremiah 31:37 This is what the Lord says:“Only if the heavens above can be measured    and the foundations of the earth below be searched out
will I reject all the descendants of Israel    because of all they have done,”declares the Lord.

New covenant is 2nd chance. What he quotes refers to promise prior to  second temple era. And guess what happen during 2nd temple era. Jews were shamed by God after rejecting Jesus who were to preach covenant only to Israelites. New Covenant can not be Greek New Testament as the content of greek gospels are meant for gentiles while God promised new covenant with the peoples mentioned only in Jer 31:31.

Yet your religion has man making the first move...

Of course that why we have prophets. As God ensure that His Laws need to be preached and spread. Followers of prophet keep on spreading the message for generations and generations. It is up to mankind to accept it or not. And they will be judged for their actions in afterword

~~
Christians preach God crucified for our salvation a message of Love that can be understood all around the world without a single reference to the bible...

If you read Israelite scriptures. God do not need to be crucified to give salvation to His creation. Romans seems to interpret wrongly about how God gives salvation that is by becoming a creation that is son of man and need to die on cross, and later wake up again.

like black muslim said, such hypothesis will only remain as supposition. It is something that will never happen. Why? the answer lies in the scriptures.
If you believe in God and what was sent in Israelite scripture. You will understand that God have promised that many nations will receive guidance. Thus telling that God will not abandon his creations and let them being misguided. God's Law will remain known to mankind till the Hour reaches them.

well in Islam, you can not imagine about God using using the concept of His creations and try to relate to it about the existence/nature/attributes of God.
Almighty God be like a family? Almighty God like mixture of space,time,matter..? Almighty God like spirit? Almighty God like flesh? All of those are things created by God.

That is why in Islam , one need to strive hard fulfilling what was ordained by God. to be righteous so that the reward in the afterlife is to meet God the creator.
