VERILY, [O believer,] it is We who have bestowed from on high this Qur'an upon thee, step by step - truly a bestowal from on high! 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 and glorify your Lord morning and evening; 25 And worship Him (a portion) of the night. And glorify Him through the livelong night. 26 Surely men love what hastes away and forget the grievous day (ahead). 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 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 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
