Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So wait patiently for the command of your Lord and do not yield to any sinful or disbelieving person among them (people). 24 Mention the Name of your Lord, mornings and evenings. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 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 admits unto His grace everyone who wills [to be admitted]; but as for the evildoers - for them has He readied grievous suffering [in the life to come]. 31
