We have revealed the Qur'an to you gradually; 23 So wait for your Lord's command, and do not follow any sinner or disbeliever among them. 24 And remember the Name of thy Lord at dawn and in the evening 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Verily those love the herein, and leave in front of them a heavy day. 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 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
