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 remember the name of your Lord morning and evening. 25 And worship Him (a portion) of the night. And glorify Him through the livelong 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 We strengthened their joints; and, when We will, We shall exchange their likes. 28 Verily this is an admonition; then whosoever will, may choose a way unto his Lord. 29 And what will you wish, except if Allah wills; indeed Allah is All Knowing, Wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
