Abu Musa Al-Ashʿari used to lay great stress on the question of urination and he used to say, "If anyone from Bani Israel happened to soil his clothes with urine, he used to cut that portion away." Hearing that, Hudhaifa said to Abu Wail, "I wish he (Abu Musa) didn't (lay great stress on that matter)." Hudhaifa added, "Messenger of Allah ﷺ went to the dumps of some people and urinated while standing."  

كَانَ أَبُو مُوسَى الأَشْعَرِيُّ يُشَدِّدُ فِي الْبَوْلِ وَيَقُولُ إِنَّ بَنِي إِسْرَائِيلَ كَانَ إِذَا أَصَابَ ثَوْبَ أَحَدِهِمْ قَرَضَهُ فَقَالَ حُذَيْفَةُ لَيْتَهُ أَمْسَكَ أَتَى رَسُولُ اللَّهِ ﷺ سُبَاطَةَ قَوْمٍ فَبَالَ قَائِمًا
