4. Ibn Mahbub has narrated from ‘Abd al-Rahman ibn Al-Hajjaj from abu al- Hassan Musa عليه السلام who has said the following about two people reviling: “Abu al-Hassan Musa عليه السلام has said, ‘Of the two people reviling each other, the initiator is more unjust. He bears his own sin and the sin of his companion as long as he does not apologize to the oppressed.’”
