To pass urine while standing and sitting

Narrated Hudhaifa:

Once the Prophet went to the dumps of some people and passed urine while standing. He then asked for water and so I brought it to him and he performed ablution.

حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنْ حُذَيْفَةَ، قَالَ أَتَى النَّبِيُّ ﷺ سُبَاطَةَ قَوْمٍ فَبَالَ قَائِمًا، ثُمَّ دَعَا بِمَاءٍ، فَجِئْتُهُ بِمَاءٍ فَتَوَضَّأَ.
