Anas said that the Prophet (ﷺ) used to perform ablution with a <i>mudd</i> of water and wash with a <i>sa‘</i> up to five <i>mudds</i>. (Bukhari and Muslim.)

وَعَنْ أَنَسٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَوَضَّأُ بِالْمُدِّ وَيَغْتَسِلُ بِالصَّاعِ إِلَى خَمْسَةِ أَمْدَادٍ
