We have revealed the Qur'an to you gradually; 23 Therefore wait patiently for the command of your Lord, and obey not from among them a sinner or an ungrateful one. 24 And celebrate the name of thy Lord morning and evening, 25 And worship Him (a portion) of the night. And glorify Him through the livelong 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; and, when We will, We shall exchange their likes. 28 This is indeed an advice; so whoever wishes may take the path towards his Lord. 29 And you do not please except that Allah please, surely Allah is Knowing, Wise; 30 He maketh whom He will to enter His mercy, and for evil-doers hath prepared a painful doom. 31
