Lo! We, even We, have revealed unto thee the Qur'an, a revelation; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 Meditate upon the name of your Lord morning and evening; 25 And during the night - worship Him; and hallow Him the livelong night. 26 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is a reminder. Let whoever wishes, take the right path to his Lord. 29 And you do not will except that Allah wills. Indeed, Allah is ever Knowing and Wise. 30 He admits to His Mercy whomsoever He pleases. As for the wrong-doers, He has prepared for them a grievous chastisement. 31
