Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 celebrate the name of thy Lord morning and evening, 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
