We have revealed the Qur'an to you gradually; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and remember the name of your Lord, morning and evening; 25 And during the night - worship Him; and hallow Him the livelong 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 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
