It is We Who have sent down the Qur'an to thee by stages. 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 And remember the name of your 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 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 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
