Narrated Abu Huraira:The Prophet said, "A group of Israelites were lost. Nobody knows what they did. But I do not see them except that they were cursed and changed into rats, for if you put the milk of a she-camel in front of a rat, it will not drink it, but if the milk of a sheep is put in front of it, it will drink it." I told this to Ka'b who asked me, "Did you hear it from the Prophet ?" I said, "Yes." Ka'b asked me the same question several times.; I said to Ka'b. "Do I read the Torah? (i.e. I tell you this from the Prophet.)"
