"If anyone tells you that the Messenger of Allah urinated while standing, do not believe him, for I (always) saw him urinating while sitting down."  

ابن ماجة:٣٠٧ – حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَسُوَيْدُ بْنُ سَعِيدٍ وَإِسْمَاعِيلُ بْنُ مُوسَى السُّدِّيُّ قَالُوا حَدَّثَنَا شَرِيكٌ عَنِ الْمِقْدَامِ بْنِ شُرَيْحِ بْنِ هَانِئٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ مَنْ حَدَّثَكَ

أَنَّ رَسُولَ اللَّهِ ﷺ بَالَ قَائِمًا فَلاَ تُصَدِّقْهُ أَنَا رَأَيْتُهُ يَبُولُ قَاعِدًا

Collected by Ibn Ḥibbān, Suyūṭī

ذِكْرُ خَبَرٍ قَدْ يُوهِمُ غَيْرَ الْمُتَبَحِّرِ فِي صِنَاعَةِ الْعِلْمِ أَنَّهُ مُضَادٌّ لِخَبَرِ حُذَيْفَةَ الَّذِي ذَكَرْنَاهُ

ibnhibban:1430 – ʿImrān b. Mūsá b. Mujāshiʿ > ʿUthmān b. Abū Shaybah > Sharīk > al-Miqdām b. Shurayḥ from his father > ʿĀʾishah > Man Ḥaddathak

[Machine] The Prophet of Allah (peace and blessings be upon him) used to urinate while standing, so I refute the claim that I saw him urinating while sitting.  

ابن حبّان:١٤٣٠ – أَخْبَرَنَا عِمْرَانُ بْنُ مُوسَى بْنِ مُجَاشِعٍ قَالَ حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ قَالَ حَدَّثَنَا شَرِيكٌ عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ «مَنْ حَدَّثَكَ

أَنَّ نَبِيَّ اللَّهِ ﷺ كَانَ يَبُولُ قَائِمًا فَكَذِّبْهُ أَنَا رَأَيْتُهُ يَبُولُ قَاعِدًا»
