(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 And celebrate the name of thy Lord morning and evening, 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 We created them, and We strengthened their joints; and, when We will, We shall exchange their likes. 28 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-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
