Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 And mention the name of your Lord [in prayer] morning and evening 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Behold, they [who are unmindful of God] love this fleeting life, and leave behind them [all thought of] a grief-laden Day. 27 We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration. 28 Verily this is an admonition; then 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 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
