Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And, remember the Name of your Lord at the dawn and in the evening; 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
