حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، قَالَ سَمِعْتُ يَحْيَى، قَالَ أَخْبَرَنِي بُشَيْرُ بْنُ يَسَارٍ، أَنَّ سُوَيْدَ بْنَ النُّعْمَانِ ـ رضى الله عنه ـ أَخْبَرَهُ أَنَّهُ، خَرَجَ مَعَ النَّبِيِّ صلى الله عليه وسلم عَامَ خَيْبَرَ، حَتَّى إِذَا كَانُوا بِالصَّهْبَاءِ ـ وَهْىَ مِنْ خَيْبَرَ وَهْىَ أَدْنَى خَيْبَرَ ـ فَصَلَّوُا الْعَصْرَ، فَدَعَا النَّبِيُّ صلى الله عليه وسلم بِالأَطْعِمَةِ، فَلَمْ يُؤْتَ النَّبِيُّ صلى الله عليه وسلم إِلاَّ بِسَوِيقٍ، فَلُكْنَا فَأَكَلْنَا وَشَرِبْنَا، ثُمَّ قَامَ النَّبِيُّ صلى الله عليه وسلم فَمَضْمَضَ وَمَضْمَضْنَا، وَصَلَّيْنَا.
