(Muhammad), We have revealed the Quran to you in gradual steps. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And celebrate the name of thy Lord morning and evening, 25 And prostrate for Him in a part of the night, and proclaim His purity into the 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 strengthened their forms, and when We will, We can change their likenesses with [complete] alteration. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
