Narrated Aisha, Ummul Mu'minin:

The Prophet ﷺ used to wash himself with a sa' (of water) and perform ablution with a mudd (of water).

Abu Dawud said: This tradition has also been narrated by Aban on the authority of Qatadah. In this version he said: "I herd safiyyah."

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ ﷺ كَانَ يَغْتَسِلُ بِالصَّاعِ وَيَتَوَضَّأُ بِالْمُدِّ . قَالَ أَبُو دَاوُدَ رَوَاهُ أَبَانُ عَنْ قَتَادَةَ قَالَ سَمِعْتُ صَفِيَّةَ .
