1. Purification
١۔ كِتَابُ الطَّهَارَةِ
It was narrated from Anas bin Malik that the Messenger of Allah ﷺ went around all his wives and only performed Ghusl once. (Using translation from Nasāʾī 263)
أَنَّ رَسُولَ اللهِ ﷺ «طَافَ عَلَى نِسَائِهِ فِي لَيْلَةٍ بِغُسْلٍ وَاحِدٍ»
The Prophet used to go round to all his wives with one bath. (Using translation from Ibn Mājah 588)
أَنَّ رَسُولَ اللهِ ﷺ كَانَ «يَطُوفُ عَلَى نِسَائِهِ فِي غُسْلٍ وَاحِدٍ»
