Sa’ad ibn Abdillah from Muhammad ibn al-Husayn from al-Sindi ibn al-Rabi' from Ali ibn Ahmad ibn Abi Nasr from his father from Jamil ibn Darraj from Muhammad ibn Muslim from Abu Ja’far عليه السلام, peace be upon him: Imam al-Baqir عليه السلام said: “If a person is killed and only flesh, without bone, is found. Then the funeral prayer is not performed over him. But if bone is found without flesh, the funeral prayer is performed over him.”
