Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 therefore be patient under the Judgement of your Lord, and do not obey either the sinner or the unbeliever. 24 And celebrate the name of thy 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 [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 indeed an advice; so whoever wishes may take the path towards his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
