Book 47: To perform ablution with one Mudd of water. (Mudd is practically 2/3 of the kilogram)

Sahih al-Bukhari 201

Anas (r.a) reported: ‘The Prophet (saw) used to wash – or [he said] used to take a bath – using between one ṣāʿ to five mudd [of water], and to perform ablution he would use only one mudd.’
