[Machine] I heard Abu Huraira while he was in the house of Umm al-Darda saying that the Messenger of Allah ﷺ said, "There are three acts that constitute disbelief in Allah: tearing the garment, wailing and lamenting, and slandering one's lineage." (Authentic in its chain of narrators, but they did not record it.)
سَمِعْتُ أَبَا هُرَيْرَةَ وَهُوَ فِي بَيْتِ أُمِّ الدَّرْدَاءِ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ ثَلَاثَةٌ مِنَ الْكُفْرِ بِاللَّهِ شَقُّ الْجَيْبِ وَالنِّيَاحَةُ وَالطَّعْنُ فِي النَّسَبِ «صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ»
