The Messenger of Allah ﷺ said, "When one of you fights his brother, let him avoid striking the face, for Allah created Adam in his image."
قال رسول الله ﷺ: إذا قاتل أحدكم أخاه فليجتنب الوجه فإن الله خلق آدم على صورته.
Muslim narrated it in "Righteousness and Kinship Ties" (2612:115) through various routes from Muthanna bin Saeed, from Qatada, from Abu Ayub, from Abu Hurairah, who mentioned it.
