Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And mention the name of your Lord [in prayer] morning and evening 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
