It is We Who have sent down the Qur'an to thee by stages. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 and glorify your Lord morning and evening; 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 This surely is a reminder: Therefore whosoever desires may take the way to his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and 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
