Observe the service of prayer from the sun's declining from the meridian to the darkening of the night, and the recitation at dawn. Indeed the Recitation at dawn is palpably evident. 78 And during the night wake up and pray, as an additional prayer: it may well be that your Lord will raise you to a station of praise and glory." 79 Say: "O my Lord! Let my entry be by the Gate of Truth and Honour, and likewise my exit by the Gate of Truth and Honour; and grant me from Thy Presence an authority to aid (me)." 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 And We reveal by means of the Qur'an that which is a healing and a mercy unto the believers, and it only increaseth the wrong-doers 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, "Everyone does as he wants. Your Lord knows best who has the right guidance." 84
