Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Remember the name of thy Lord at morn and evening. 25 And during part of the night adore Him, and give glory to Him (a) long (part of the) night. 26 Verily those love the herein, and leave in front of them a heavy 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 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
