We have indeed, sent down to you the Koran, a (clear) sending, 23 Wherefore persevere thou with the commandment of thy Lord, and obey not thou of them, any sinner or ingrate. 24 And celebrate the name of thy Lord morning and evening, 25 and prostrate yourself before Him at night, and extol His Glory during the long watches of the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration. 28 Indeed, this is a reminder, so he who wills may take to his Lord a way. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He maketh whomsoever He listeth to enter His mercy. And the wrong-doers! for them He hath gotten ready a torment afflective. 31
