Imam Sadiq (a.s) said: “A man complained to God's Prophet (a.s) about his neighbor. The Prophet (a.s) turned his face away. The man did it again but the Prophet paid no attention to him. He complained for the third time. This time the Prophet looked at Imam Ali (a.s), Salman and Meghdad and said: “Go and announce that God and His angels damn whoever bothers his neighbors.”
