Establish Prayer from the declining of the sun to the darkness of the night; and hold fast to the recitation of the Qur'an at dawn, for the recitation of the Qur'an at dawn is witnessed. 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 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 And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss. 82 And when We show favour unto man, he turneth away and withdraweth on his side; and when evil toucheth him he is ever despairing. 83 Say: Each one doth according to his rule of conduct, and thy Lord is Best Aware of him whose way is right. 84
