Sayyiduna Ibn Umar (may Allah be pleased with them both) narrates from Sayyiduna Zayd bin al-Khattab (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade killing the snakes that live in houses, which are the dwellers of the homes.
No one narrated this hadith from Ja'far (may Allah have mercy on him) except Fayyad (may Allah have mercy on him).
