Arabic Text
حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا عَمْرُو بْنُ مُرَّةَ، سَمِعْتُ سَعِيدَ بْنَ الْمُسَيَّبِ، قَالَ قَدِمَ مُعَاوِيَةُ الْمَدِينَةَ آخِرَ قَدْمَةٍ قَدِمَهَا، فَخَطَبَنَا فَأَخْرَجَ كُبَّةً مِنْ شَعَرٍ قَالَ مَا كُنْتُ أَرَى أَحَدًا يَفْعَلُ هَذَا غَيْرَ الْيَهُودِ، إِنَّ النَّبِيَّ صلى الله عليه وسلم سَمَّاهُ الزُّورَ. يَعْنِي الْوَاصِلَةَ فِي الشَّعَرِ.
