The Messenger of Allah ﷺ used to bathe together with one of his wives from a single vessel.
حدثنا عثمان بن عمر أخبرنا شعبة عن عبد الله بن عبد الله بن جبر قال سمعت
إن كان رسول الله ﷺ ليغتسل والمرأة من نسائه من الإناء الواحد
Its isnad is sahih. Abdullah bin Abdullah bin Jabr, also said to be Jabir, is reliable, and the hadith was mentioned previously at 12095.
