Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And mention the name of your Lord [in prayer] morning and evening 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
