حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا سُلَيْمَانُ يَعْنِي التَّيْمِيَّ، عَنْ أَبِي عُثْمَانَ، عَنْ عَبْدِ اللَّهِ بْنِ عَامِرٍ، عَنِ الزُّبَيْرِ بْنِ الْعَوَّامِ، أَنَّ رَجُلًا، حَمَلَ عَلَى فَرَسٍ يُقَالُ لَهَا غَمْرَةُ أَوْ غَمْرَاءُ وَقَالَ فَوَجَدَ فَرَسًا أَوْ مُهْرًا يُبَاعُ فَنُسِبَتْ إِلَى تِلْكَ الْفَرَسِ فَنُهِيَ عَنْهَا.
