We have indeed, sent down to you the Koran, a (clear) sending, 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 the name of your Lord morning and evening. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 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 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits into His mercy, whomever He wills; and for the unjust He has kept prepared a painful punishment. 31
