Establish the prayer at the decline of the sun till the darkening of the night and the Koran recital at dawn. Surely, the Koran recital at dawn is witnessed. 78 And as for the night, keep vigil a part of it, as a work of supererogation for thee; it may be that thy Lord will raise thee up to a laudable station. 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 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 Whenever We bestow favours upon man, he arrogantly turns away and draws aside; and whenever evil visits him, he is in utter despair. 83 Say, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
