1. Purification
١۔ كِتَابُ الطَّهَارَةِ
"The Messenger of Allah ﷺ came out to us with a small leather shield in his hand. He put it down, then he sat behind it and urinated toward it. Some of the people said: 'Look, he is urinating like a woman.' He heard that and said: 'Do you not know what happened to the companion of the Children of Israel? If they got any urine on themselves they would clip that part of their garments off. Their companion told them not to do that and he was punished in his grave.'" (Using translation from Nasāʾī 30)
خَرَجَ عَلَيْنَا رَسُولُ اللهِ ﷺ وَفِي يَدِهِ كَهَيْئَةِ الدَّرَقَةِ فَوَضَعَهَا ثُمَّ جَلَسَ فَبَالَ إِلَيْهَا فَقَالَ بَعْضُ الْقَوْمِ انْظُرُوا يَبُولُ كَمَا تَبُولُ الْمَرْأَةُ فَسَمِعَهُ فَقَالَ «أَوَمَا عَلِمْتَ مَا أَصَابَ صَاحِبَ بَنِي إِسْرَائِيلَ كَانُوا إِذَا أَصَابَهُمْ شَيْءٌ مِنَ الْبَوْلِ قَطَعُوهُ بِالْمَقَارِيضِ فَنَهَاهُمْ فَعُذِّبَ فِي قَبْرِهِ»
