(Muhammad), We have revealed the Quran to you in gradual steps. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 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 strengthened their joints; and whenever We wish, We can change their faces entirely. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
