Establish worship at the going down of the sun until the dark of night, and (the recital of) the Qur'an at dawn. Lo! (the recital of) the Qur'an at dawn is ever witnessed. 78 And rise from thy sleep and pray during part of the night [as well,] as a free offering from thee, and thy Sustainer may well raise thee to a glorious station [in the life to come]. 79 And say: 'My Lord, lead me in with a just ingoing, and lead me out with a just outgoing; grant me authority from Thee, to help me.' 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 We send down (stage by stage) in the Qur'an that which is a healing and a mercy to those who believe: to the unjust it causes nothing but loss after 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: Every one acts according to his manner; but your Lord best knows who is best guided in the path. 84
