Truly, it is We who have revealed to you the Quran, a gradual revelation. 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 remember the Name of thy Lord at dawn and in the evening 25 and during the night prostrate ourself before Him, and extol His glory for a long part of the night. 26 Verily those love the herein, and leave in front of them a heavy day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits to His mercy whomever He wants. For the unjust He has prepared a painful punishment. 31
