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.
أَنَّ النَّبِيَّ ﷺ دَعَا بِقَدَحٍ فِيهِ مَاءٌ فَغَسَلَ يَدَيْهِ وَوَجْهَهُ فِيهِ وَمَجَّ فِيهِ
The Prophet asked for a tumbler containing water and washed both his hands and face in it and then threw a mouthful of water in the tumbler and said to both of us (Abu Musa and Bilal), "Drink from the tumbler and pour some of its water on your faces and chests."
دَعَا النَّبِيُّ ﷺ بِقَدَحٍ فِيهِ مَاءٌ فَغَسَلَ يَدَيْهِ وَوَجْهَهُ فِيهِ وَمَجَّ فِيهِ ثُمَّ قَالَ لَهُمَا اشْرَبَا مِنْهُ وَأَفْرِغَا عَلَى وُجُوهِكُمَا وَنُحُورِكُمَا
