(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 your Lord morning and evening; 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
