الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ طِبَاقًا ۖ مَّا تَرَىٰ فِي خَلْقِ الرَّحْمَٰنِ مِن تَفَاوُتٍ ۖ فَارْجِعِ الْبَصَرَ هَلْ تَرَىٰ مِن فُطُورٍ (3)
(67:3) Who created the seven heavens one upon another. *6 You will see no incongruity in the Merciful One's creation. *7 Turn your vision again, can you see any flaw? *8
*6) For explanation, see E.N. 34 of AI-Baqarah, E.N 2 of Ar-Ra`d, E.N. 8 of Al-Hijr, E.N. 113 of Al-Hajj, E.N. 15 of Al-Mu'minun, E.N. 5 of As-Saaffat, E.N. 90 of Al-Mu'min.
*7) Literally, tafawut is disproportion: two things being out of accord and agreement with each other. So, the Divine words mean: "You will not see any indiscipline, any disorder and discordance anywhere in the universe, there is nothing disjointed and out of proportion in this world created by Allah: all its parts are well connected and in perfect harmony and coordination.
*8) The word futur means a crack, rift, fissure, or a thing's being split and broken. The verse means to say that the whole universe is so closely well-knit and everything in it, from a particle on the earth to the huge galaxies, so well connected and coherent that the continuity of the system of the universe seems to break nowhere, however hard one may try to probe and investigate. (For further explanation, see E.N. 8 of Surah Qaf).
