Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Abi bin Umm Haram (may Allah be pleased with him) says that I heard the Messenger of Allah (peace and blessings be upon him) say: "You must use senna and honey, for in them is a cure for every disease except «سام»." It was asked, "What is the meaning of «سام»?" He (peace and blessings be upon him) said: "Death."
