Sunan Ibn Majah 270
The Book of Purification and its Sunnah
The quantity of water required for ablution and bathing from a state of sexual impurity
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُؤَمَّلِ بْنِ الصَّبَّاحِ، وَعَبَّادُ بْنُ الْوَلِيدِ، قَالاَ حَدَّثَنَا بَكْرُ بْنُ يَحْيَى بْنِ زَبَّانَ، حَدَّثَنَا حِبَّانُ بْنُ عَلِيٍّ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلِ بْنِ أَبِي طَالِبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يُجْزِئُ مِنَ الْوُضُوءِ مُدٌّ وَمِنَ الْغُسْلِ صَاعٌ . فَقَالَ رَجُلٌ لاَ يُجْزِئُنَا . فَقَالَ قَدْ كَانَ يُجْزِئُ مَنْ هُوَ خَيْرٌ مِنْكَ وَأَكْثَرُ شَعَرًا . يَعْنِي النَّبِيَّ ـ صلى الله عليه وسلم ـ .
'Abdullah bin Muhammed bin 'Aqil bin Abu Talib narrated from his father that his grandfather said: "The Messenger of Allah said: 'A Mudd is sufficient for the ablution and a Sa' is sufficient for the bath.' A man said: 'It is not sufficient for us.'" He (the narrator) said: "It was sufficient for one who is better than you and had more hair" meaning the Prophet.
