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 Mention the Name of your Lord, mornings and evenings. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 28 Surely this is a reminder, so whoever pleases takes to his Lord a way. 29 But you cannot will it unless God wills [to show you that way]: for, behold, God is indeed all-seeing, 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
