Surely We have sent down the Koran on thee, a sending down; 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Remember the name of thy Lord at morn and evening. 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 This chapter is a reminder. Let those who want, seek guidance from their Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
