Mansur contradicted him, he reported it from Mujahid from ibn 'Abbas, but he did not mention Tawus in it.Abu Dawud engaged in extensive contemplation to determine the Hadith that would best honor the Prophet for the inaugural chapter of his compilation.

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، عَنْ شُعْبَةَ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ حُذَيْفَةَ ـ رضى الله عنه ـ قَالَ لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم، أَوْ قَالَ لَقَدْ أَتَى النَّبِيُّ صلى الله عليه وسلم سُبَاطَةَ قَوْمٍ فَبَالَ قَائِمًا.
Narrated Hudhaifa: I saw Allah's Messenger (ﷺ) coming (or the Prophet (ﷺ) came) to the dumps of some people and urinated there while standing.

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا شَيْبَانُ، عَنْ يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا شَرِبَ أَحَدُكُمْ فَلاَ يَتَنَفَّسْ فِي الإِنَاءِ، وَإِذَا بَالَ أَحَدُكُمْ فَلاَ يَمْسَحْ ذَكَرَهُ بِيَمِينِهِ، وَإِذَا تَمَسَّحَ أَحَدُكُمْ فَلاَ يَتَمَسَّحْ بِيَمِينِهِ ".
Narrated Abu Qatada: Allah's Messenger (ﷺ) said, "When you drink (water), do not breath in the vessel; and when you urinate, do not touch your penis with your right hand. And when you cleanse yourself after defecation, do not use your right hand."
