عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ قَالَ كَانَ الْمَاءُ مَاءُ غُسْلِهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ حِينَ غَسَّلُوهُ بَعْدَ وَفَاتِهِ يَسْتَنْقِعُ فِي جُفُونِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَكَانَ عَلِيٌّ يَحْسُوهُ
It is narrated from Ja'far bin Muhammad that when the noble Companions gave Ghusl (ritual bath) to the Prophet ﷺ, the water from the Prophet’s ﷺ Ghusl was collected in his ﷺ vessels, and Ali (may Allah be pleased with him) would drink it sip by sip.
