[Machine] When the Messenger of Allah ﷺ used to cleanse himself from impurity, he would call for something like a container and take it with his hand. He would begin by pouring water on the right side of his head, then on the left side. Then he would take water with both of his hands and pour it over his head, saying, "With them, I am washing my head."  

كَانَ رَسُولُ اللهِ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَيْءٍ نَحْوَ الْحِلَابِ وَأَخَذَهُ بِكَفِّهِ فَبَدَأَ بِشِقِّ رَأْسِهِ الْأَيْمَنِ ثُمَّ الْأَيْسَرِ ثُمَّ أَخَذَ بِكَفَّيْهِ الْمَاءَ فَقَالَ بِهِمَا عَلَى رَأْسِهِ  

[Machine] That the Messenger of Allah ﷺ used to perform ablution (washing) in a container of this size and Abu Asim showed us a container the size of the container in his hand, and it was like a cup that holds eight pounds. Then he would pour water on the right side of his head and then pour water on the left side of his head, and then he would cup his hands and pour water over the middle of his head.  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَغْتَسِلُ فِي حِلَابٍ قَدْرَ هَذَا وَأَرَانَا أَبُو عَاصِمٍ قَدْرَ الْحِلَابِ بِيَدِهِ فَإِذَا هُوَ كَقَدْرِ كُوزٍ يَسَعُ ثَمَانِيَةَ أَرْطَالٍ ثُمَّ يَصُبُّ عَلَى شِقِّ رَأْسِهِ الْأَيْمَنِ ثُمَّ يَصُبُّ عَلَى شِقِّ رَأْسِهِ الْأَيْسَرِ ثُمَّ يَأْخُذُ بِكَفَّيْهِ فَيَصُبُّ وَسَطَ رَأْسِهِ
