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 And remember thou the name of thy Lord in the morning and in the 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 Verily! These (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard). 27 We created them and strengthened their joints; and whenever We wish, We can change their faces entirely. 28 Surely this is a Reminder; so he who will, takes unto his Lord a way. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will and as for the Zalimun, (polytheists, wrong-doers, etc.) He has prepared a painful torment. 31
