(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 glorify the name of your Lord morning and evening. 25 Prostrate before Him and glorify Him extensively during the night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 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 whomever He wants. For the unjust He has prepared a painful punishment. 31
