Sahih Muslim | Book 34 | Chapter 3

Narrated by Abu Sa'id al-Khudri
Abu Sa'id al-Khudri reported Allah's Messenger (may peace be upon him) as saying: You would tread the same path as was trodden by those before you inch by inch and step by step so much so that if they had entered into the hole of the lizard, you would follow them in this also. We said: Allah's Messenger, do you mean Jews and Christians (by your words) "those before you"? He said: Who else (than those two religious groups)?
