The Prophet ﷺ 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 Kaʿb who asked me, "Did you hear it from the Prophet ﷺ ?" I said, "Yes." Kaʿb asked me the same question several times.; I said to Kaʿb. "Do I read the Torah? (i.e. I tell you this from the Prophet.)"  

عَنِ النَّبِيِّ ﷺ قَالَ فُقِدَتْ أُمَّةٌ مِنْ بَنِي إِسْرَائِيلَ لاَ يُدْرَى مَا فَعَلَتْ وَإِنِّي لاَ أُرَاهَا إِلاَّ الْفَارَ إِذَا وُضِعَ لَهَا أَلْبَانُ الإِبِلِ لَمْ تَشْرَبْ وَإِذَا وُضِعَ لَهَا أَلْبَانُ الشَّاءِ شَرِبَتْ فَحَدَّثْتُ كَعْبًا فَقَالَ أَنْتَ سَمِعْتَ النَّبِيَّ ﷺ يَقُولُهُ قُلْتُ نَعَمْ قَالَ لِي مِرَارًا فَقُلْتُ أَفَأَقْرَأُ التَّوْرَاةَ
