Surely We have sent down the Koran on thee, a sending down; 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 Remember the name of thy Lord at morn and evening. 25 and during some of the night, and prostrate thyself before Him, and extol His limitless glory throughout the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 But you will not desire except as God wills. Verily He is all-knowing and all-wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
