We have indeed, sent down to you the Koran, a (clear) sending, 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 and glorify your Lord morning and evening; 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
