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 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 We send down in the Quran that which is healing and a mercy to those who believe; as for the evil-doers, it only increases their loss. 82 And when We bless man, he turns away, and withdraws aside; but when evil visits him, he is in despair. 83 Say: 'Every man works according to his own manner; but your Lord knows very well what man is best guided as to the way.' 84
