Musnad Ahmad Hadith 9326

It is narrated from Abu Hurairah (may Allah be pleased with him) that the mouse is from a deformed nation, and its sign is that if camel’s milk is placed before it, it does not drink it, but if goat’s milk is placed before it, it drinks it. Ka’b Ahbar (may Allah have mercy on him), who was a newly converted Jewish scholar, said: “Did you yourself hear this hadith from the Noble Prophet (ﷺ)?” I said: “Has the Torah been revealed to me?”
