It was narrated that Jabir bin 'Abdullah said: "The Prophet, Abu Bakr and 'Umar ate some bread and meat, and they did not perform ablution (after that)."
حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَخْبَرَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، وَعَمْرِو بْنِ دِينَارٍ، وَعَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ أَكَلَ النَّبِيُّ ـ صلى الله عليه وسلم ـ وَأَبُو بَكْرٍ وَعُمَرُ خُبْزًا وَلَحْمًا وَلَمْ يَتَوَضَّئُوا .
