58وَتَوَكَّلْ عَلَى ٱلْحَىِّ ٱلَّذِى لَا يَمُوتُ وَسَبِّحْ بِحَمْدِهِۦ ۚ وَكَفَىٰ بِهِۦ بِذُنُوبِ عِبَادِهِۦ خَبِيرًا
59ٱلَّذِى خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ وَمَا بَيْنَهُمَا فِى سِتَّةِ أَيَّامٍ ثُمَّ ٱسْتَوَىٰ عَلَى ٱلْعَرْشِ ۚ ٱلرَّحْمَـٰنُ فَسْـَٔلْ بِهِۦ خَبِيرًا
[58-59] O Muhammad trust in that Allah Who is Ever-Living and will never die' Glorify Him with His praise, for He alone is sufficient to be aware of the sins of His servants. In six days He created the earth and the heavens and all that is between them; then He established Himself on the "Throne" (of the Kingdom of the universe).72 (He is) the Merciful: as to His Glory, ask the one who knows.
72For explanation of "Throne", see E.N.'s 41, 42 of Al-A'raf, E.N. 4 of Yunus, and E.N. 7 of Hud.
It is difficult to say what exactly is mean by "six days" Here a "day" thay mean a period of time or an ordinary day of this world. For explanation of the "day", see E.N.'s 11 to 15 of Surah Ha Mim Sajdah.
