It is We Who have sent down the Qur'an to thee by stages. 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 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 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 But your willing shall be of no avail until Allah Himself so wills. Surely Allah is All-Knowing, Most Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
