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 remember the name of your Lord, morning and evening; 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
