(Muhammad), We have revealed the Quran to you in gradual steps. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 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 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
