(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And glorify the name of your Lord morning and evening. 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
