Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) was asked: "Is slaughter (dhakah) only at the throat and the hollow above the chest (labbah)?" He (peace and blessings be upon him) replied: "Even if you (in such a case) were to strike its thigh with a spear or a sharp object, it would suffice for you."
No one narrated this hadith from Ja'far bin Sulayman (may Allah have mercy on him) except Bakr bin al-Sharud (may Allah have mercy on him), and it is not narrated from Sayyiduna Anas (may Allah be pleased with him) except with this chain.
