Sunan an-Nasa'i 29
It was narrated that 'Aishah said:
"Whoever tells you that the Messenger of Allah ﷺ urinated standing up, do not believe him, for he would not urinate except while squatting."
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا شَرِيكٌ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ مَنْ حَدَّثَكُمْ أَنَّ رَسُولَ اللَّهِ ﷺ بَالَ قَائِمًا فَلاَ تُصَدِّقُوهُ مَا كَانَ يَبُولُ إِلاَّ جَالِسًا .
