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  

[Machine] Abu Musa used to urinate in a bottle and say, "When one of the children of Israel used to experience the need to urinate, he would dig a hole and urinate in it." Hudhaifah said, "I wish that your companion would not enforce this strictness. I have seen myself following the Prophet ﷺ until we reached a place called Subata, and he stood up to urinate just as any of you would. So I moved away from him, and he said, 'Come closer.'" So I approached him until I was by his side.  

أَنَّ أَبَا مُوسَى كَانَ يَبُولُ فِي قَارُورَةٍ وَيَقُولُ إِنَّ بَنِي إِسْرَائِيلَ كَانَ إِذَا أَصَابَ أَحَدَهُمُ الْبَوْلُ قَرَضَ مَكَانَهُ قَالَ حُذَيْفَةُ وَدِدْتُ أَنَّ صَاحِبَكُمْ لَا يُشَدِّدُ هَذَا التَّشْدِيدَ لَقَدْ رَأَيْتُنِي نَتَمَاشَى مَعَ رَسُولِ اللهِ ﷺ فَانْتَهَيْنَا إِلَى سُبَاطَةٍ فَقَامَ يَبُولُ كَمَا يَبُولُ أَحَدُكُمْ فَذَهَبْتُ أَتَنَحَّى عَنْهُ فَقَالَ ادْنُهْ فَدَنَوْتُ مِنْهُ حَتَّى كُنْتُ عِنْدَ عَقِبِهِ
