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 Say a supererogatory prayer at the hour of the first watch: Your Lord may raise you to a most exalted station. 79 And say: My Lord! make me to enter a goodly entering, and cause me to go forth a goodly going forth, and grant me from near Thee power to assist (me). 80 Say, 'Truth has come and falsehood has been banished; it is doomed to banishment.'" 81 And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust. 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
