(O Prophet), indeed We have revealed the Qur'an to you in portions. 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 your Lord at the dawn and in the 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 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
