Surely We have sent down the Koran on thee, a sending down; 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 glorify 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 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 This is indeed an advice; so whoever wishes may take the path towards 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
