النسائي:٣٦٤٢ – أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ قَالَ حَدَّثَنَا خَالِدٌ قَالَ حَدَّثَنَا سَعِيدٌ قَالَ حَدَّثَنَا قَتَادَةُ عَنْ شَهْرِ بْنِ حَوْشَبٍ أَنَّ ابْنَ غَنْمٍ ذَكَرَ أَنَّ ابْنَ خَارِجَةَ ذَكَرَ لَهُ

أَنَّهُ شَهِدَ رَسُولَ اللَّهِ ﷺ يَخْطُبُ النَّاسَ عَلَى رَاحِلَتِهِ وَإِنَّهَا لَتَقْصَعُ بِجِرَّتِهَا وَإِنَّ لُعَابَهَا لَيَسِيلُ فَقَالَ رَسُولُ اللَّهِ ﷺ فِي خُطْبَتِهِ إِنَّ اللَّهَ قَدْ قَسَّمَ لِكُلِّ إِنْسَانٍ قِسْمَهُ مِنَ الْمِيرَاثِ فَلاَ تَجُوزُ لِوَارِثٍ وَصِيَّةٌ
