Narrated Abu Musa:
حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ ، قَالَ حَدَّثَنَا أَبُو أُسَامَةَ ، عَنْ بُرَيْدٍ ، عَنْ أَبِي بُرْدَةَ ، عَنْ أَبِي مُوسَى ، أَنَّ النَّبِيَّ صلى الله عليه وسلم دَعَا بِقَدَحٍ فِيهِ مَاءٌ، فَغَسَلَ يَدَيْهِ وَوَجْهَهُ فِيهِ وَمَجَّ فِيهِ.
Once the Prophet (ﷺ) asked for a tumbler containing water. He washed his hands and face in it and also threw a mouthful of water in it.
