We have indeed, sent down to you the Koran, a (clear) sending, 23 Therefore be patient with constancy to the Command of thy Lord, and hearken not to the sinner or the ingrate among them. 24 Mention the Name of your Lord, mornings and evenings. 25 and in the night prostrate to Him; and exalt Him for a long night. 26 Indeed these people love what they have, the fleeting one, and have forsaken the immensely important day behind them. 27 We created them, and We strengthened their joints, but, when We will, We shall indeed exchange their likes. 28 VERILY, all this is an admonition: whoever, then, so wills, may unto his Sustainer find a way. 29 Yet you will not unless Allah wills; surely, Allah is the Knower, the Wise. 30 He admits whom He wills into His mercy; but the wrongdoers - He has prepared for them a painful punishment. 31
