Say your prayers from the decline of the sun, until nightfall; and at dawn -- the recitation at dawn is indeed witnessed. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 79 Say, "Lord, grant me an honourable entrance and an honourable exit, and sustain me with Your power." 80 And say: "Truth (i.e. Islamic Monotheism or this Quran or Jihad against polytheists) has come and Batil (falsehood, i.e. Satan or polytheism, etc.) has vanished. Surely! Batil is ever bound to vanish." 81 We sent down of the Koran that which is a healing and a mercy to believers, but to the harmdoers it does not increase them, except in loss. 82 When We are gracious to man he turns away and moves aside; yet when evil befalls him he begins to despair. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
