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."  

أَنَّ النَّبِيَّ ﷺ كَانَ يَغْتَسِلُ بِالصَّاعِ وَيَتَوَضَّأُ بِالْمُدِّ  

The Prophet ﷺ used to take a bath with a sa' (of water) and perform ablution with a mudd (of water)  

كَانَ رَسُولُ اللَّهِ ﷺ يَغْتَسِلُ بِالصَّاعِ وَيَتَوَضَّأُ بِالْمُدِّ  

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

أَنَّ النَّبِيَّ ﷺ تَوَضَّأَ فَأُتِيَ بِإِنَاءٍ فِيهِ مَاءٌ قَدْرُ ثُلُثَىِ الْمُدِّ  

The Prophet ﷺ performed ablution with a vessel which contained two rotls (of water) and took a bath with a sa’ (of water).1 Abu Dawud Said : This tradition has berated on the authority of Anas through a different chain. This version mentions: “He performed ablution with one makkuk. “It makes no mention of two rotls. 2 Abu Dawud said : This tradition has also been narrated by Yahya b. Adam from Sharik. But this chain mentions Ibn Jabr b. ‘Atik instead of ‘ Abd Allah b. Jabr. Abu Dawud Said : This tradition has also been narrated by Sufyan from ‘Abd Allah b. ‘Isa. This chain mentions the name Jabr b. ‘Abd Allah instead of ‘Abd Allah b. Jabr. Abu Dawud Said : I heard Ahmad b. Hanbal say : one sa’ measures five rotls. It was the sa’ of Ibn Abi Dhi’b and also of the Prophet ﷺ.  

كَانَ النَّبِيُّ ﷺ يَتَوَضَّأُ بِإِنَاءٍ يَسَعُ رَطْلَيْنِ وَيَغْتَسِلُ بِالصَّاعِ
