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, morning and evening; 25 And bow in homage part of the night, and glorify Him far into the night. 26 Surely these love the transitory and neglect a grievous day before them. 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 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
