(50) باب مَا ذُكِرَ عَنْ بَنِي إِسْرَائِيلَ
Narrated Abu Sa`id:
The Prophet (ﷺ) said, "You will follow the wrong ways, of your predecessors so completely and literally that if they should go into the hole of a mastigure, you too will go there." We said, "O Allah's Messenger (ﷺ)! Do you mean the Jews and the Christians?" He replied, "Whom else?" (Meaning, of course, the Jews and the Christians.)
