We have indeed, sent down to you the Koran, a (clear) sending, 23 So be patient for the decision of your Lord and do not obey from among them a sinner or ungrateful [disbeliever]. 24 Meditate upon the name of your Lord morning and evening; 25 And during night, prostrate yourself to Him (i.e. the offering of Maghrib and 'Isha' prayers), and glorify Him a long night through (i.e. Tahajjud prayer). 26 Those people [who are unmindful of God] aspire for immediate gains, and put behind them a Heavy Day. 27 We, even We, created them, and strengthened their frame. And when We will, We can replace them, bringing others like them in their stead. 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 whoever He will into His grace and has prepared a painful punishment for the evil doers. 31
