[Machine] Regarding the Prophet ﷺ , Ibn Abbas wrote to him asking about it. Al-Ash'ari wrote to him, "Indeed, you are a man of your time, and I have not heard anything from the Prophet ﷺ about it except that I was with the Prophet ﷺ when he wanted to urinate. He stood up and urinated against a wall there and said, 'Indeed, the Children of Israel used to collect their urine with a qarad (vessel). So, when one of you wants to urinate, let him turn away from his urine.'"  

عَنِ النَّبِيِّ ﷺ فَكَتَبَ إِلَيْهِ ابْنُ عَبَّاسٍ يَسْأَلُهُ عَنْهَا فَكَتَبَ إِلَيْهِ الْأَشْعَرِيُّ إِنَّكَ رَجُلٌ مِنْ أَهْلِ زَمَانِكَ وَإِنِّي لَمْ أُحَدِّثْ عَنِ النَّبِيِّ ﷺ مِنْهَا بِشَيْءٍ إِلَّا أَنِّي كُنْتُ مَعَ النَّبِيِّ ﷺ فَأَرَادَ أَنْ يَبُولَ فَقَامَ إِلَى دَمِثِ حَائِطٍ هُنَاكَ وَقَالَ «إِنَّ بَنِي إِسْرَائِيلَ كَانَ إِذَا أَصَابَ أَحَدَهُمُ الْبَوْلُ قَرَضَهُ بِالْمِقْرَاضِ فَإِذَا أَرَادَ أَحَدُكُمْ أَنْ يَبُولَ فَلْيَرْتَدْ لِبَوْلِهِ»
