(O Prophet), indeed We have revealed the Qur'an to you in portions. 23 Await, then, in all patience thy Sustainer's judgment, and pay no heed to any of them, who is a wilful sinner or an ingrate; 24 And, remember the Name of your Lord at the dawn and in the evening; 25 And prostrate for Him in a part of the night, and proclaim His purity into 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 Verily! This (Verses of the Quran) is an admonition, so whosoever wills, let him take a Path to his Lord (Allah). 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
