We have indeed, sent down to you the Koran, a (clear) sending, 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 Prostrate before Him and glorify Him extensively during the night. 26 Verily they love (the good of this world) that is hastily obtainable and are oblivious of the burdensome Day ahead of them. 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 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He is Merciful to whom He will; but, for the harmdoers He has prepared for them a painful punishment. 31
