Truly, it is We who have revealed to you the Quran, a gradual revelation. 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 And remember thou the name of thy Lord in the morning and in the 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 We have created them and have given them strength. Had We wanted, We could have replaced them with another people like them. 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 For He admits into His mercy whomsoever He will; as for the evildoers, He has prepared for them a painful chastisement. 31
