It is narrated from Sayyiduna Jabir (may Allah be pleased with them both) that on the day of (the treaty of) Hudaybiyah the Prophet (peace and blessings be upon him) ordered them that seven men at a time should share in one camel (as a sacrifice).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Sharik except Ishaq al-Azraq."
