فَلَا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ ۝ وَإِنَّهُ لَقَسَمٌ لَّوْ تَعْلَمُونَ عَظِيمٌ ۝ إِنَّهُ لَقُرْآنٌ كَرِيمٌ

This is a happening so great as to be owesome. A person who gives serious consideration to this system functioning in space, will be compelled to admit that the Creator of this universe is unimaginably Mighty. Then the Book coming from such a Creator should also be certainly great, and the Qur’an is undoubtedly such a great Book. The Quran reached the Prophet through the angels in exactly the same condition as it was in the preserved tablet (lawh mahfudh) and it is still intact in that same condition today. There is no other book of ancient times which has been so perfectly preserved. This in itself is proof of the Book’s (the Quran’s) greatness. The misfortune of one who does not obtain guidance from such a book is incalculable.
