The Prophet ﷺ said: When I was taken up to heaven I passed by people who had nails of copper and were scratching their faces and their breasts. I said: Who are these people, Gabriel? He replied: They are those who were given to back biting and who aspersed people's honour. Abu Dawud said: Yahya b. 'Uthman has also transmitted it from Baqiyyah, there is no mention of Anas in it.  

قَالَ رَسُولُ اللَّهِ ﷺ لَمَّا عُرِجَ بِي مَرَرْتُ بِقَوْمٍ لَهُمْ أَظْفَارٌ مِنْ نُحَاسٍ يَخْمِشُونَ وُجُوهَهُمْ وَصُدُورَهُمْ فَقُلْتُ مَنْ هَؤُلاَءِ يَا جِبْرِيلُ قَالَ هَؤُلاَءِ الَّذِينَ يَأْكُلُونَ لُحُومَ النَّاسِ وَيَقَعُونَ فِي أَعْرَاضِهِمْ  

"مرَرْتُ لَيلَةَ أُسْرى بِى علَى قَوْم يخْمِشُونَ وجُوهَهُم بأَظَافِيرِهِم، فَقُلتُ: يا جبْرِيلُ، منْ هؤُلاءِ؟ قَال: هؤُلاءِ الَّذِين يغْتَابُونَ الناس، ويقَعُونَ في أَعْراضِهمْ".
