We have revealed the Qur'an to you gradually; 23 So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever. 24 Mention the Name of your Lord, mornings and evenings. 25 and in the night prostrate to Him; and exalt Him for a 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 We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 But you cannot will it unless God wills [to show you that way] -- God is indeed all-knowing and wise -- 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
