Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 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 to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
