from the Prophet ﷺ that he said, "Do you know what ʿi’ḍah (calumny, slander, or causing separation) is?" They said, "Allah and His Messenger know best." The Prophet said, "It is spreading news between people to ruin their relationships."
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ: «أَتَدْرُونَ مَا الْعِضَةُ؟» قَالُوا: اللهُ وَرَسُولُهُ أَعْلَمُ، قَالَ: «نَقْلُ الْحَدِيثِ مِنْ بَعْضِ النَّاسِ إِلَى بَعْضٍ لِيُفْسِدَ بَيْنَهُمْ»
