It is We Who have sent down the Qur'an to thee by stages. 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And remember the Name of thy Lord at dawn and in the evening 25 And during the night prostrate to Him and exalt Him a long [part of the] night. 26 Indeed, these love the hasty life, and are heedless and leave behind them a heavy Day. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 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 admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
