(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 every morning and afternoon [i.e. offering of the Morning (Fajr), Zuhr, and 'Asr prayers]. 25 And part of the night, prostrate thyself to Him; and glorify Him a long night through. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous 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 Lo! this is an Admonishment, that whosoever will may choose a way unto his Lord. 29 But ye will not, except as Allah wills; for Allah is full of Knowledge and Wisdom. 30 He admits whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
