It is We Who have sent down the Qur'an to thee by stages. 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and bear in mind thy Sustainer's name at morn and evening 25 And bow in homage part of the night, and glorify Him far into the night. 26 These people (disbelievers) love the worldly life and neglect the terrifying day which will come. 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
