اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنِ اَلنَّضْرِ عَنْ مُحَمَّدِ بْنِ أَبِي حَمْزَةَ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يَقُولُ:« كَانَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ يَغْتَسِلُ بِصَاعٍ وَ إِذَا كَانَ مَعَهُ بَعْضُ نِسَائِهِ يَغْتَسِلُ بِصَاعٍ وَ مُدٍّ».
Narrated by al-Husayn ibn Sa'id, from al-Nadr, from Muhammad ibn Abi Hamzah, from Mu'awiyah ibn Ammar, who said:
I heard Abu Abdullah عليه السلام say: "The Messenger of Allah سبحانه وتعالى (peace be upon him and his family) used to perform ghusl with a sa‘ of water, and if one of his wives was with him, they would perform ghusl with a sa‘ and a mudd."
