[Machine] That the Messenger of Allah ﷺ used to perform ablution like this.  

أَنَّ رَسُولَ اللهِ ﷺ «كَانَ يَغْتَسِلُ بِمِثْلِ هَذَا»  

[Machine] The Messenger of Allah ﷺ used to bathe in a container called al-Qadah while standing.  

كَانَ رَسُولُ اللهِ ﷺ «يَغْتَسِلُ فِي الْقَدَحِ وَهُوَ الْفَرَقُ»  

"I heard Abu Salamah say: 'I entered upon 'Aishah and her foster-brother was with her. He asked her about the Ghusl of the Prophet ﷺ. She called for a vessel in which was a Sa' of water, then she concealed herself and performed Ghusl and poured water over her head three times.'" (Using translation from Nasāʾī 227)  

سَمِعْتُ أَبَا سَلَمَةَ يَقُولُ دَخَلْتُ عَلَى عَائِشَةَ وَأَخُوهَا مِنَ الرَّضَاعَةِ فَسَأَلَهَا عَنْ غُسْلِ النَّبِيِّ ﷺ؟ «فَدَعَتْ بِإِنَاءٍ فِيهِ قَدْرُ صَاعٍ فَسَتَرَتْ سِتْرًا فَأَفْرَغَتْ عَلَى رَأْسِهَا ثَلَاثًا»  

"We argued about Ghusl in the presence of jabir in 'Abdullah, and Jabir said: 'One Sa' of water is sufficient for ghusl from Janabah.' We said: 'One Sa' is not enough and neither is two.' Jabir said: 'It was sufficient for one who was better than you and had more hair.'" (Using translation from Nasāʾī 230)  

جَابِرٌ يَكْفِي مِنَ الْغُسْلِ مِنَ الْجَنَابَةِ صَاعٌ مِنْ مَاءٍ قُلْنَا مَا يَكْفِي صَاعٌ وَلَا صَاعَانِ قَالَ جَابِرٌ قَدْ كَانَ يَكْفِي مَنْ كَانَ خَيْرًا مِنْكُمْ وَأَكْثَرَ شَعْرًا
