A man went to Imam Hassan (AS) complaining of his neighbor’s nuisance. The Imam said:
“Perform a two-Rakat salaat after evening prayer and then say: O Mighty in prowess, O Mighty, O You whose plan is strong, O You who have abased all creatures before Your Might! Save me from the evil of such a person as You will.”
The man acted according to Imam Hassan’s order. At midnight a wailing was heard and he was informed that his neighbor had died.
