حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ حَنْظَلَةَ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلمإِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَىْءٍ نَحْوِ الْحِلاَبِ فَأَخَذَ بِكَفِّهِ فَبَدَأَ بِشِقِّ رَأْسِهِ الأَيْمَنِ ثُمَّ الأَيْسَرِ ثُمَّ أَخَذَ بِكَفَّيْهِ فَقَالَ بِهِمَا عَلَى رَأْسِهِ ‏.‏

'Aishah reported

When the Messenger of Allah (ﷺ) performed ghusl from janabah, he would call for something like a vessel (hilab), take water in his palm, and begin with the right side of his head, then the left, then take water in both his palms and pour it over his head.
