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 celebrate the name of thy Lord morning and evening, 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is indeed a Reminder, so that he who will, takes a path to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
