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 glorify the name of your Lord morning and evening. 25 And during the night - worship Him; and hallow Him the livelong night. 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
