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 bear in mind thy Sustainer's name at morn and evening 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Surely men love what hastes away and forget the grievous day (ahead). 27 We created them and fixed their bones and joints; and We could replace them when We like with others like them. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the 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
