Narrated Sufyan:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ عُبَيْدِ اللَّهِ ، سَمِعَ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ خِلاَلٌ مِنْ خِلاَلِ الْجَاهِلِيَّةِ الطَّعْنُ فِي الأَنْسَابِ وَالنِّيَاحَةُ، وَنَسِيَ الثَّالِثَةَ، قَالَ سُفْيَانُ وَيَقُولُونَ إِنَّهَا الاِسْتِسْقَاءُ بِالأَنْوَاءِ.
'Ubaidullah said: "I heard Ibn `Abbas saying, "Following are some traits of the people of the pre- Islamic period of ignorance (i) to defame the ancestry of other families, (ii) and to wail over the dead."
