We have indeed, sent down to you the Koran, a (clear) sending, 23 therefore be patient under the Judgement of your Lord, and do not obey either the sinner or the unbeliever. 24 Mention the Name of your Lord, mornings and evenings. 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 Lo! these love fleeting life, and put behind them (the remembrance of) a grievous day. 27 We created them and made firm their make, and when We please We will bring in their place the likes of them by a change. 28 Verily this is an Exhortation; so let him who so will take a way to his Lord. 29 Yet ye will not, unless Allah willeth. Lo! Allah is Knower, Wise. 30 He will admit to His Mercy whom He will; But the wrong-doers,- for them has He prepared a grievous Penalty. 31
