Verily! It is We Who have sent down the Quran to you (O Muhammad SAW) by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 Remember the name of thy Lord at morn and evening. 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Surely these love the transitory and neglect a grievous day before 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 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
