Mukhtasar Bukhari (Abridged) 1393 — The best wealth for Muslims

Narrated Abu Huraira (may Allah be pleased with him) from the Prophet (peace and blessings of Allah be upon him) that he said: "Some people among the Children of Israel disappeared; no one knew what they had done. Their forms were transformed. I think that those people became mice, because if camel's milk is placed before a mouse, it does not drink it (in the religion of the Children of Israel, the camel was forbidden), but if goat's milk is placed, it drinks it." So I (Abu Huraira, may Allah be pleased with him) narrated this hadith to Ka'b (may Allah be pleased with him), and he said, "Did you hear this hadith from the Prophet (peace and blessings of Allah be upon him)?" I said, "Yes." (Ka'b, may Allah be pleased with him) kept asking me the same thing repeatedly, so I said, "(If I had not heard it from the Messenger of Allah, peace and blessings of Allah be upon him,) then do I read the Torah?"
