Musannaf Ibn Abi Shaybah 27340 — A man returning another's greeting

Malik bin Aws bin al-Hadathan said that Sayyiduna Abu Dharr (may Allah be pleased with him) returned from Syria and entered the mosque, while Sayyiduna Uthman (may Allah be pleased with him) was also in the mosque. He said: As-salamu alaykum (peace be upon you). He replied: Wa alaykum as-salam (and upon you be peace). How are you, O Abu Dharr? He said: I am well. How are you, O Uthman? He replied: I too am well.
