(Muhammad), We have revealed the Quran to you in gradual steps. 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or 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 love the transitory and neglect a grievous day before them. 27 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 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 whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
