Establish prayer at the decline of the sun [from its meridian] until the darkness of the night and [also] the Qur'an of dawn. Indeed, the recitation of dawn is ever witnessed. 78 And from [part of] the night, pray with it as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station. 79 And say, "My Lord, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting 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 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 And when We make life pleasant unto man, he turneth away and is averse; and when ill toucheth 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
