Sahih al-Bukhari 3305

Musa ibn Ismaʿil narrated to us: Wuhaib narrated to us, from Khalid, from Muhammad, from Abu Hurayra (may Allah be pleased with him), from the Prophet ﷺ, who said: ‘A community of the Children of Israel disappeared, and it is not known what became of it. I can only think that they were mice: when camel milk was placed before them, they would not drink it, but when sheep’s milk was placed before them, they would drink it.’ I related this to Kaʿb, and he said, ‘Did you hear the Prophet ﷺ say this?’ I replied, ‘Yes.’ He asked me this repeatedly. I said, ‘Am I reading the Torah?’
