Musnad Abu Ya'la al-Mawsili 155:191

'Abd al-A'la ibn Hammad al-Narsi narrated to us, Wahib narrated to us, Khalid narrated to us, from Muhammad ibn Sirin, from Abu Hurayrah, who said: The Messenger of Allah (ﷺ) said: "A nation from the Children of Israel was lost; it is not known what they did. I do not see them as anything but the rats. Do you not see that when camel milk is brought near to them, they do not drink it, but when sheep milk is brought near to them, they drink it?" Abu Hurayrah said: I narrated this hadith to Ka'b, and he said: "Did you hear this from the Messenger of Allah (ﷺ)?" He said it to him repeatedly. Abu Hurayrah said: "Was the Torah revealed to me?"
