We have revealed the Qur'an to you gradually; 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 and remember the name of your Lord, morning and evening; 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Surely these men love the hasty world, and leave be behind them a heavy day. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But you cannot will, unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. 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
