الترمذي:١٣٤١حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ أَنْبَأَنَا عَلِيُّ بْنُ مُسْهِرٍ وَغَيْرُهُ عَنْ مُحَمَّدِ بْنِ عُبَيْدِ اللَّهِ عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ

أَنَّ النَّبِيَّ ﷺ قَالَ فِي خُطْبَتِهِ الْبَيِّنَةُ عَلَى الْمُدَّعِي وَالْيَمِينُ عَلَى الْمُدَّعَى عَلَيْهِ هَذَا حَدِيثٌ فِي إِسْنَادِهِ مَقَالٌ وَمُحَمَّدُ بْنُ عُبَيْدِ اللَّهِ الْعَرْزَمِيُّ يُضَعَّفُ فِي الْحَدِيثِ مِنْ قِبَلِ حِفْظِهِ ضَعَّفَهُ ابْنُ الْمُبَارَكِ وَغَيْرُهُ
