عن أبي هريرة رضي الله عنه قال قال النبي صلى الله عليه وسلم تجد من شر الناس يوم القيامة عند الله ذا الوجهين الذي يأتي هؤلاء بوجه وهؤلاء بوجه (صحيح البخاري #6058، صحيح مسلم #2526)

Hazrat Abu Hurairah (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “You will find that among the most evil of people in the court of Allah Ta‘ala, on the Day of Qiyaamah, is the one who is two faced; he comes to these people with one face, and to those people with another face (i.e. he pretends to side with each group and expresses his support for them with wrong motives and intentions).”
