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 Remember the name of thy Lord at morn and evening. 25 And prostrate for Him in a part of the night, and proclaim His purity into the long night. 26 Behold, they [who are unmindful of God] love this fleeting life, and leave behind them [all thought of] a grief-laden Day. 27 It is We Who creared them and made them firm of make. And whenever We list, We can replace them with others like unto them. 28 This is an admonition: Whosoever will, let him take a (straight) Path to his Lord. 29 And ye will not, unless Allah willeth. Verily Allah is ever Knowing, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
