We have revealed the Qur'an to you gradually; 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 24 And remember 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 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 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 admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
