(Muhammad), We have revealed the Quran to you in gradual steps. 23 So persevere with the command of your Lord and do not pay any heed to the wicked and the unbelieving, 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 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 an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
