Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 And remember the name of your Lord morning and evening. 25 And during the night prostrate to Him and exalt Him a long [part of 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 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
