Say your prayer when the sun declines until the darkness of night and also at dawn. Dawn is certainly witnessed (by the angels of the night and day). 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 (Muhammad), say, "Lord, make me enter through a path that will lead to the Truth and come out of an exit that will take me to the Truth. Give me helpful authority. 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 send down in the Qur’an that which is a cure for the Muslims, and a mercy – and it increases only ruin for the unjust. 82 Yet when We bestow favors upon mankind he turns his back and withdraws to one side. But when evil befalls him, he despairs. 83 Say: 'Each human works in his own manner. But your Lord knows very well who is best guided on the way' 84
