"I heard Anas bin Malik say: 'The Messenger of Allah ﷺ used to perform Wudu' with a Makkuk (cup) and Ghusl with five Makkuks (cups).'"  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ بِمَكُّوكٍ وَيَغْتَسِلُ بِخَمْسَةِ مَكَاكِيَّ  

"I heard 'Abbad bin Tamim narrate from my grandmother - who was Umm 'Umarah bint Ka'b - that the Prophet ﷺ performed Wudu', and he was brought a vessel in which there were two-thirds of a Mudd." Shu'bah said: "I remember that he washed his forearms and started rubbing them, and he wiped the inside of his ear, but I do not remember whether he wiped the outside of them."  

عَنْ جَدَّتِي وَهِيَ أُمُّ عُمَارَةَ بِنْتُ كَعْبٍ أَنَّ النَّبِيَّ ﷺ تَوَضَّأَ فَأُتِيَ بِمَاءٍ فِي إِنَاءٍ قَدْرَ ثُلُثَىِ الْمُدِّ قَالَ شُعْبَةُ فَأَحْفَظُ أَنَّهُ غَسَلَ ذِرَاعَيْهِ وَجَعَلَ يَدْلُكُهُمَا وَيَمْسَحُ أُذُنَيْهِ بَاطِنَهُمَا وَلاَ أَحْفَظُ أَنَّهُ مَسَحَ ظَاهِرَهُمَا
