Surat Al Isra' (93-94)

{أَوْ يَكُونَ لَكَ بَيْتٌ مِّن زُخْرُفٍ أَوْ تَرْقَى فِي السَّمَاء وَلَن نُّؤْمِنَ لِرُقِيِّكَ حَتَّى تُنَزِّلَ عَلَيْنَا كِتَاباً نَّقْرَؤُهُ قُلْ سُبْحَانَ رَبِّي هَلْ كُنتُ إَلاَّ بَشَراً رَّسُولاً} (الإسراء: 93)

93- Or you shall have a house of gold or to ascend to the sky while we are looking at you, and we will not believe your ascent until you send down a book in which is written that we have to follow you.

Tell them in wonder: May Allah be Exalted and Glorified. I am only a human messenger, and miracles are not from the manufacture of messengers. It is not polite that the Messengers ask their lord to send miracles to them if He does not allow them.

Allah is the most knowledgeable of His Servants and that may fix them to send it down, and there are some matters which cannot be answered such as the descent of Allah and His Angles. They left the Qur'an behind their backs after they had known it was the great miracle indicated the prophethood of the Prophet (peace be upon him).

{وَمَا مَنَعَ النَّاسَ أَن يُؤْمِنُواْ إِذْ جَاءهُمُ الْهُدَى إِلاَّ أَن قَالُواْ أَبَعَثَ اللّهُ بَشَراً رَّسُولاً} (الإسراء: 94)

94- What prevented most people of believing in the Messenger after the revelation was sent down to them correlated with miracles is their denial and disapproval of being a human messenger.
