(Muhammad), We have revealed the Quran to you in gradual steps. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 Mention the Name of your Lord, mornings and evenings. 25 And during the night - worship Him; and hallow Him the livelong night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
