عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((شُعْبَتَانِ مِنْ أَمْرِ الْجَاهِلِيَّةِ لَا يَتْرُكُهُمَا النَّاسُ أَبَدًا: النِّيَاحَةُ وَالطَّعْنُ فِي النَّسَبِ))
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: There are two practices from the era of ignorance which people will never abandon: wailing over the dead and casting aspersions on lineage.
