"(He) Who created seven heavens one above another"—some of them above others, the thickness of each heaven being a journey of five hundred years, and between every two heavens is a journey of five hundred years. "You see no discrepancy in the creation of the Most Merciful"—meaning: difference; that is: they are uniform. "So look again"—meaning: gaze at the heaven. "Do you see any rifts"—meaning: any cracks; that is: you will see no cracks in them.
Muhammad said: It is among the speech of the Arabs: 'The camel's fang split' (fatara) if it tore the flesh and appeared.
﴿الَّذِي خلق سبع سماوات طباقا﴾ بَعْضُهَا فَوْقَ بَعْضٍ، غِلَظُ كُلِّ سَمَاء مِنْهَا مسيرَة خَمْسمِائَة عَامٍ، وَبَيْنَ كُلِّ سَمَاءَيْنِ مسيرةُ خَمْسمِائَة عَامٍ ﴿مَا تَرَى فِي خَلْقِ الرَّحْمَن من تفَاوت﴾ أَيْ: اخْتِلافٌ؛ يَعْنِي: مُسْتَوِيَةً ﴿فَارْجِعِ الْبَصَر﴾ أَيْ: فَانْظُرْ إِلَى السَّمَاءِ ﴿هَلْ ترى من فطور﴾ مِنْ شُقُوقٍ؛ أَيْ: أَنَّكَ لَا تَرَى فِيهَا شُقُوقًا.
قَالَ مُحَمَّدٌ: مِنْ كَلامِ الْعَرَبِ: فَطَرَ نابُ الْبَعِيرِ إِذَا شقَّ اللَّحْمَ فَظَهَرَ (١)
