We have revealed the Qur'an to you gradually; 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 and remember the name of your Lord, morning and evening; 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 It is We Who created them, and We have made their joints strong; but, when We will, We can substitute the like of them by a complete change. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
