Question: Verse 21:32  وَجَعَلْنَا السَّمَاءَ سَقْفًا مَّحْفُوظًا وَهُمْ عَنْ آيَاتِهَا مُعْرِضُون The word (محفوظاً) does it mean (protected) or (protective) in other words is it the sky protects us or is it that the sky is protected.  Is it objective or subjective Answering: It is both objective and subjective. The sky is both a protector for us and is also protected from harm.  A SAQF سَقْفًا (ceiling) is something that is above one's head and is both protective and protected.  MAHFOOTH محفوظ (protected, protective) is derived from HIFTH (keep, memorize as in memorizing the Quran).  If I give you $1000 to keep until I return from a trip, then the money is in your HIFTH (keep and protection).  Visit also Aurora Lights Hadith:    Allah Almighty in the Glorious Quran said that earth is:        -  Spherical: "egg-shaped" [1].        -  Is rotating around itself.        -  Is moving in space in curvy orbits [2].        -  Is in constant motion.        -  Is suspended in space.        -  Is swimming in space.        -  Is traveling through the constantly expanding universe [3].        -  The sunsetless North Pole miracle in the Glorious Quran [4].  At the top of the North Pole, the sun never sets [4], and I showed the video for that, and also quoted the scientific sources for that. Also in the lands near by, it almost never sets either, and I quoted sources for that as well, and also showed pictures of the "polar night" skies on these lands that are near the sunsetless North Pole.    (Click to play clip by physicist, Brian Cox) They also spoke almost unintelligibly (18:93), the Glorious Quran says.  They hardly spoke intelligibly (18:93).  Historians have proven that the Barbarians of the North used to speak unintelligibly.  The actual meaning of the word "Barbarian" is someone who speaks unintelligibly.       He saw the Aurora Lights covering: Aurora Lights Hadith    Prophet Muhammad, peace be upon him, saw the aurora lights covering the horizons of space above the earth when he was taken up to Heaven: Narrated Abdullah: "Regarding the Verse: “Indeed he (Muhammad) did see. Of the Signs of his Lord, The Greatest!” (Quran 53.18) That the Prophet had seen a green carpet spread all over the horizon of the sky قَالَ رَأَى رَفْرَفًا أَخْضَرَ سَدَّ أُفُقَ السَّمَاء." (Translation of Sahih Bukhari, Volume 4, Book 54, Number 456) Visit also: Islamic proof that the sun prostrates to Allah Almighty when it is above Mecca.    Regarding Dhil-Qarnayn (literally means "man of two horns"), Allah Almighty said this about his journey to the farthest northern lands and people: ‏18:90 حتى اذا بلغ مطلع الشمس وجدها تطلع على قوم لم نجعل لهم من دونها ستر "Until he reached near حتى اذا بلغ where the sun is up مطلع الشمس, he found it above وجدها تطلع على people قوم whom We made no cover for them from it لم نجعل لهم من دونها ستر.  (The Noble Quran, 18:90)" Noble Verse(s) 18:91 Rodwell: [018:091]  Thus it was. And we had full knowledge of the forces that were with him. Arabic (Read from right to left.  Also, all png image files: [1] [2].  Quran Moral Code (100s of them)]): ‏18:91 كذلك وقد احطنا بما لديه خبرا     Prophet Muhammad "did see" (Quran 53.18) the Aurora Lights covering the horizons above the earth from space.  Dhil-Qarnayn went up to the farthest northern lands where the sun is up, and "Thus it was", Allah Almighty completed the "full knowledge" regarding Dhil-Qarnayn's mission.  This further supports the story below about Dhil-Qarnayn's journey to the farthest northern lands and people (The sunsetless [4] North Pole Quran-miracle).  They also spoke almost unintelligibly (18:93), the Glorious Quran says.  They hardly spoke intelligibly (18:93).  For example, can you read or say this: "Vaðlaheiðarvegavinnuverkfærageymsluskúrslyklakippuhringurinn" ??  This is an actual word. Historians have proven that the Barbarians of the North used to speak unintelligibly.  The actual meaning of the word "Barbarian" is someone who speaks unintelligibly.  The description of the people of the North, whose North Pole is truly sunsetless (see ample pictures), perfectly fits the Barbarians of the Vikings in the Scandinavian and other Barbarians in the near by lands: The early Muslims believed that Dhil Qarnayn reached the people of the farthest norths of the earth.  The following is a map of Al-Sharif Al-Idrisi in year 1154 giving the geographic location of where Dhil Qarnayn went according to the understanding of the early Muslims of Noble Verses 18:83-100: Dhil-Qarnayn literally means "man of two horns" Dhil = One who has. قرنين Qarnayn = two horns.  Qarnayn is a dual plural of Qarn (horn). Three or more horns is Quroon, in Arabic.    Noble Verses 53:18 and 18:91 are also prophetically linked together; that Prophet Muhammad also saw what Dhil-Qarnayn ذي القرنين  saw.  Also visit:  Aurora Lights Hadith    Other pronunciations to "Dhil Qarnayn"ذي القرنين  name:  Zul-qarnain, Dhul Qurnain, Dhu'l Qarnain, Zulqarnain, Dhu'l-Qarneyn, Dhu'lkarnein, Dhul-Qarnain, Dhu'l Qarnain, Dhool Karnain, Zul-Qarnain, Dhoulkarnain.   (Video from NASA filming the Green Carpet Aurora Lights from space) Again, Prophet Muhammad, peace be upon him, saw the aurora lights covering the horizons of space above the earth when he was taken up to Heaven: Narrated Abdullah: "Regarding the Verse: “Indeed he (Muhammad) did see. Of the Signs of his Lord, The Greatest!” (Quran 53.18) That the Prophet had seen a green carpet spread all over the horizon of the sky قَالَ رَأَى رَفْرَفًا أَخْضَرَ سَدَّ أُفُقَ السَّمَاء."(Translation of Sahih Bukhari, Volume 4, Book 54, Number 456) Visit also: Islamic proof that the sun prostrates to Allah Almighty when it is above Mecca.        -  The Glorious Quran also speaks about many earths [5] and not just earth.        -  The Glorious Quran predicts 11 planets in our solar system [6].    In the end, Allah Almighty uses the Glorious Quran to "...Thus doth God leave to stray whom He pleaseth, and guide whom He pleaseth..." (74:31).  The infidels misuse the Glorious Quran to find "scientific errors".  The Glorious Quran is Allah Almighty's Perfect Divine Holy Book.  It contains no scientific error.  Visit the following example and the link to see 1000s of Numerical and Scientific Miracles: 1-  The root for message and all of its derivatives, such as messenger and others occurs 513 times throughout the Glorious Quran.  The Prophets' and Messengers', peace be upon them, actual names (Muhammad, Moses, Noah, Abraham, Lot etc....) were also all combined mentioned 513 times in the Glorious Quran.  The detailed breakdown of all of this is thoroughly listed here. Coincidence?  See 1,000s of examples! [1]. (zip file). Quran's Stunning Numerical & Scientific Miracles. Stunning Prophecies [2] [3]
