5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about a man who kills a wasp. He (the Imam) said, ‘If it is by mistake then there is nothing on him.’ I said, ‘No, it is done knowingly.’ He (the Imam) said, ‘Feed a certain amount of food.’ I then asked, ‘Is it so even if it attacks me?’ He (the Imam) said, ‘Anything that attacks, it is permissible for you to kill it.’”
