bukhari:252ʿAbdullāh b. Muḥammad > Yaḥyá b. Ādam > Zuhayr > Abū Isḥāq > Abū Jaʿfar

While I and my father were with Jabir bin ʿAbdullah, some people asked him about taking a bath. He replied, "A Saʿ of water is sufficient for you." A man said, "A Saʿ is not sufficient for me." Jabir said, "A Saʿ was sufficient for one who had more hair than you and was better than you (meaning the Prophet)." And then Jabir (put on) his garment and led the prayer.  

البخاري:٢٥٢حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ قَالَ حَدَّثَنَا زُهَيْرٌ عَنْ أَبِي إِسْحَاقَ قَالَ حَدَّثَنَا أَبُو جَعْفَرٍ أَنَّهُ كَانَ عِنْدَ جَابِرِ بْنِ عَبْدِ اللَّهِ هُوَ وَأَبُوهُ وَعِنْدَهُ قَوْمٌ فَسَأَلُوهُ عَنِ الْغُسْلِ فَقَالَ يَكْفِيكَ صَاعٌ فَقَالَ رَجُلٌ مَا يَكْفِينِي فَقَالَ

جَابِرٌ كَانَ يَكْفِي مَنْ هُوَ أَوْفَى مِنْكَ شَعَرًا وَخَيْرٌ مِنْكَ ثُمَّ أَمَّنَا فِي ثَوْبٍ
