Indeed, it is We who have sent down to you, [O Muhammad], the Qur'an progressively. 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 thy Lord at dawn and in the evening 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
