(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And mention the name of your Lord [in prayer] morning and evening 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
