"My maternal aunt Maimunah told me that she and the Messenger of Allah (ﷺ) used to perform Ghusl from one vessel."
أَخْبَرَنَا يَحْيَى بْنُ مُوسَى، عَنْ سُفْيَانَ، عَنْ عَمْرٍو، عَنْ جَابِرِ بْنِ زَيْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَخْبَرَتْنِي خَالَتِي، مَيْمُونَةُ أَنَّهَا كَانَتْ تَغْتَسِلُ وَرَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ إِنَاءٍ وَاحِدٍ ‏.‏
