Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever witnessed. 78 And some part of the night awake for it, a largess for thee. It may be that thy Lord will raise thee to a praised estate. 79 And say thou: O my Lord! cause me to enter a rightful entrance and cause me to go forth with a rightful outgoing, and appoint for me from before Thee an authority helpful. 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 send down (stage by stage) in the Qur'an that which is a healing and a mercy to those who believe: to the unjust it causes nothing but loss after 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: "Everyone acts according to his own disposition: But your Lord knows best who it is that is best guided on the Way." 84
