Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 so be thou patient under the judgment of thy Lord, and obey not one of them, sinner or unbeliever. 24 And celebrate the name of thy Lord morning and evening, 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 Verily those love the herein, and leave in front of them a heavy day. 27 [They will not admit to themselves that] it We who have created them and strengthened their make - and [that] if it be Our will We can replace them entirely with others of their kind. 28 This is a reminder. Let whoever wishes, take the right path 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
