عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يَتَوَضَّأُ بِالْمُدِّ وَيَغْتَسِلُ بِنَحْوِ الصَّاعِ
It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) used to perform ablution with one mudd of water and take a bath with the amount of one sa’ of water.
