Sunan Abi Dawud, Book 1, Hadith 94 (USC-MSA)

Narrated Umm Umarah: Habib al-Ansari reported: I heard Abbad ibn Tamim who reported on the authority of my grandmother, Umm Umarah, saying: The Prophet wanted to perform ablution. A vessel containing 2/3 mudd of water was brought to him.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ حَبِيبٍ الأَنْصَارِيِّ، قَالَ سَمِعْتُ عَبَّادَ بْنَ تَمِيمٍ، عَنْ جَدَّتِهِ، وَهِيَ أُمُّ عُمَارَةَ أَنَّ النَّبِيَّ صلى الله عليه وسلم تَوَضَّأَ فَأُتِيَ بِإِنَاءٍ فِيهِ مَاءٌ قَدْرُ ثُلُثَىِ الْمُدِّ ‏.‏
