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 (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 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 And We send down from the Quran that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss. 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, "Each works according to his manner, but your Lord is most knowing of who is best guided in way." 84
