We have indeed, sent down to you the Koran, a (clear) sending, 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 And remember the name of your Lord morning 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 have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and 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
