(Muhammad), We have revealed the Quran to you in gradual steps. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And remember thou the name of thy Lord in the morning and in the evening. 25 And during the night - worship Him; and hallow Him the livelong night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
