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, cause me to enter a sound entrance and to exit a sound exit and grant me from Yourself a supporting authority." 80 And say: 'The truth has come, and falsehood has vanished away; surely falsehood is ever certain 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 thou: everyone worketh after his disposition, and your Lord is the Best Knower of him who is best guided on the way. 84
