Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Surely these love the transitory and neglect a grievous day before them. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
