Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Mention the Name of your Lord, mornings and evenings. 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, but, when We will, We shall indeed exchange their likes. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
