"A bucket was brought to the Prophet; he rinsed his mouth and spat into it, and it was like musk or better than musk, and he rinsed his nostrils outside the bucket."  

رَأَيْتُ النَّبِيَّ ﷺ أُتِيَ بِدَلْوٍ فَمَضْمَضَ مِنْهُ فَمَجَّ فِيهِ مِسْكًا أَوْ أَطْيَبَ مِنَ الْمِسْكِ وَاسْتَنْثَرَ خَارِجًا مِنَ الدَّلْوِ  

Mahmud bin Rabi' remembered that the Prophet spat into a bucket from a well that belonged to them.  

عَنْ مَحْمُودِ بْنِ الرَّبِيعِ وَكَانَ قَدْ عَقَلَ مَجَّةً مَجَّهَا رَسُولُ اللَّهِ ﷺ فِي دَلْوٍ مِنْ بِئْرٍ لَهُمْ
