It is We Who have sent down the Qur'an to thee by stages. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And celebrate the name of thy Lord morning and evening, 25 And worship Him (a portion) of the night. And glorify Him through the livelong 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 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 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
