ذِكْرُ الْبَيَانِ بِأَنَّ الْقَدْرَ الَّذِي وَصَفْنَاهُ لِلِاغْتِسَالِ مِنَ الْجَنَابَةِ لَيْسَ بِقَدْرٍ لَا يَجُوزُ تَعَدِّيهِ فِيمَا هُوَ أَقَلُّ أَوْ أَكْثَرُ مِنْهُ
Anas reported that the Messenger of Allah (may peace he upon him) took a bath with five Makkuks of water and performed ablution with one Makkuk. Ibn Muthanna has used the words five Makakiyya, and Ibn Mu'adh narrated it from 'Abdullah b. 'Abdullah and he made no mention of Ibn Jabr. (Using translation from Muslim 325a)
سَمِعْتُ أَنَسًا يَقُولُ «كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ بِمَكُّوكٍ وَيَغْتَسِلُ بِخَمْسِ مَكَاكِيٍّ»
