Perform the prayer at the sinking of the sun to the darkening of the night and the recital of dawn; surely the recital of dawn is witnessed. 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 Say: 'Lord, grant me an entrance of sincerity and an exit of sincerity, and give me from Yours a victorious power' 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 THUS, step by step, We bestow from on high through this Qur'an all that gives health [to the spirit] and is a grace unto those who believe [in Us,] the while it only adds to the ruin of evildoers: 82 And when We bestow favor upon the disbeliever, he turns away and distances himself; and when evil touches him, he is ever despairing. 83 Proclaim, “Each one works according to his own pattern; and your Lord well knows him who is more upon guidance.” 84
