We have revealed the Qur'an to you gradually; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and glorify 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 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Surely this is a reminder, so whoever pleases takes to 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
