The Messenger of Allah came to the garbage dump of some people and he urinated on it standing up.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى سُبَاطَةَ قَوْمٍ فَبَالَ عَلَيْهَا قَائِمًا  

The Messenger of Allah came to the garbage dump of some people and urinated while standing up. (Hasan) Shu'bah said: "That day, 'Asim said: 'Amash reported this from Abu Wa'il, from Hudhaifah, but he did not remember it (correctly). So I asked Mansur about it, and he narrated it to me from Abu Wa'il, from Hudhaifah, that the Prophet came to a dump of some people and urinated while standing.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى سُبَاطَةَ قَوْمٍ فَبَالَ قَائِمًا قَالَ شُعْبَةُ قَالَ عَاصِمٌ يَوْمَئِذٍ وَهَذَا الأَعْمَشُ يَرْوِيهِ عَنْ أَبِي وَائِلٍ عَنْ حُذَيْفَةَ وَمَا حَفِظَهُ فَسَأَلْتُ عَنْهُ مَنْصُورًا فَحَدَّثَنِيهِ عَنْ أَبِي وَائِلٍ عَنْ حُذَيْفَةَ أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى سُبَاطَةَ قَوْمٍ فَبَالَ قَائِمًا
