Verily We! it is We Who have revealed unto thee the Qur'an, a gradual revelation. 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 your Lord, morning and evening; 25 and part of the night; bow down before Him and magnify Him through the long night. 26 As to these, they love the fleeting life, and put away behind them a Day (that will be) hard. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 This is indeed an advice; so whoever wishes may take the path towards 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 admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
