It was narrated from Hudhaifah that the Prophet (ﷺ) went to some people's garbage dump and urinated while standing. In his narration, Sulaiman bin 'Ubaidullah said:"And he wiped over his Khuffs," but Mansur did not mention the wiping. [1] [1]Meaning, in this route, since Shu'bah narrated it from both Sulaiman and Mansur.
أَخْبَرَنَا سُلَيْمَانُ بْنُ عُبَيْدِ اللَّهِ، قَالَ أَنْبَأَنَا بَهْزٌ، قَالَ أَنْبَأَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، وَمَنْصُورٌ، عَنْ أَبِي وَائِلٍ، عَنْ حُذَيْفَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم مَشَى إِلَى سُبَاطَةِ قَوْمٍ فَبَالَ قَائِمًا . قَالَ سُلَيْمَانُ فِي حَدِيثِهِ وَمَسَحَ عَلَى خُفَّيْهِ وَلَمْ يَذْكُرْ مَنْصُورٌ الْمَسْحَ .
