Hadith on Backbiting: You have eaten the flesh of your brother

Abdullah ibn Mas’ud reported: We were sitting with the Prophet, peace and blessings be upon him, when a man stood to leave, then another man spoke badly about him after he left. The Prophet said, “Pick your teeth.” The man said, “O Messenger of Allah, why should I pick my teeth when I have not eaten meat?” The Prophet said, “You have eaten the flesh of your brother.”

عَنْ عَبْدِ اللَّهِ قَالَ كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَامَ رَجُلٌ فَوَقَعَ فِيهِ رَجُلٌ مِنْ بَعْدِهِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَخَلَّلْ قَالَ وَمَا أَتَخَلَّلُ يَا رَسُولَ اللَّهِ أَكَلْتُ لَحْمًا قَالَ إِنَّكَ أَكَلْتَ لَحْمَ أَخِيكَ
