The Prophet used to take a bath with one Saor up to five Mudds (1 Sa'= Mudds) of water and used to perform ablution with one Mudd of water.

حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا مِسْعَرٌ، قَالَ حَدَّثَنِي ابْنُ جَبْرٍ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ كَانَ النَّبِيُّ ﷺ يَغْسِلُ ـ أَوْ كَانَ يَغْتَسِلُ ـ بِالصَّاعِ إِلَى خَمْسَةِ أَمْدَادٍ، وَيَتَوَضَّأُ بِالْمُدِّ.
