We have indeed, sent down to you the Koran, a (clear) sending, 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And celebrate the name of thy Lord morning and evening, 25 And bow in homage part of the night, and glorify Him far into the night. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
