BE CONSTANT in [thy] prayer from the time when the sun has passed its zenith till the darkness of night, and [be ever mindful of its] recitation at dawn: for, behold, the recitation [of prayer] at dawn is indeed witnessed [by all that is holy]. 78 As for the night there is a voluntary deed for you to keep vigil in part it. Perhaps your Lord will raise you to a praiseworthy station. 79 And pray: "O my Lord, let my entry be with honour, and let my exit be with honour, and grant me power from You which would help (sustain) 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 What We are sending down in the course of revealing the Qur'an is a healing and a grace for those who have faith; but it adds only to the ruin of the wrong-doers. 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: "Everyone acts in a manner peculiar to himself - and your Sustainer is fully aware as to who has chosen the best path." 84
