The males and females during the time of the Apostle of Allaah ( sal Allahu alayhi wa sallam ) used to perform the ablution from one vessel together. The wordings "from one vessel" occur in the version of Musaddad.
كَانَ الرِّجَالُ وَالنِّسَاءُ يَتَوَضَّئُونَ فِي زَمَانِ رَسُولِ اللَّهِ ﷺ قَالَ مُسَدَّدٌ مِنَ الإِنَاءِ الْوَاحِدِ جَمِيعًا
