Shu'bah narrated from 'Asim from Abu Wa'il from Mughirah bin Shu'bah that:
The Messenger of Allah came to the garbage dump of some people and urinated while standing up.
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.'"

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمٍ، عَنْ أَبِي وَائِلٍ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، 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 .
