It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that he was asked: "Did the Messenger of Allah (peace and blessings be upon him) use to shake hands?" He said: "Whenever the Messenger of Allah (peace and blessings be upon him) met me and I greeted him (peace and blessings be upon him) with salam, he (peace and blessings be upon him) always shook hands with me, except once, and that was the best occasion of all: I came to him (peace and blessings be upon him) while he (peace and blessings be upon him) was ill, and I bent over him (peace and blessings be upon him), and he (peace and blessings be upon him) embraced me."
This hadith is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) only with this chain; Sa'id bin Abi al-Rabi' (may Allah have mercy on him) is alone in narrating it.
