(Muhammad), We have revealed the Quran to you in gradual steps. 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 every morning and afternoon [i.e. offering of the Morning (Fajr), Zuhr, and 'Asr prayers]. 25 and part of the night; bow down before Him and magnify Him through the long night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 It is We Who created them, and strengthened their skeleton; and We can replace them with others like them, whenever We will. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He makes whom He pleases to enter into His mercy; and (as for) the unjust, He has prepared for them a painful chastisement. 31
