Surely We Ourselves have revealed the Quran to you revealing (it) in portions. 23 So wait patiently for the command of your Lord, and do not yield to anyone among them who is sinful or ungrateful; 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 Surely men love what hastes away and forget the grievous day (ahead). 27 It was We who created them and made their constitution strong, but if We wish we can replace them with others like them. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 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
