(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And celebrate the name of thy Lord morning and evening, 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
