[Machine] The Prophet ﷺ came to them in the Masjid Quba and said, "Indeed, Allah has praised you concerning cleanliness in the story of your mosque. So what is the purification that you perform?" They said, "O Messenger of Allah, we do not know anything except that we had Jewish neighbors who used to wash their backside after relieving themselves, so we washed as they did."
أَنَّ النَّبِيَّ ﷺ أَتَاهُمْ فِي مَسْجِدِ قُبَاءَ فَقَالَ «إنَّ اللهَ ﷻ قَدْ أَحْسَنَ إِلَيْكُم الثَّنَاءَ فِي الطُّهُورِ فِي قِصَّةِ مَسْجِدِكُمْ فَمَا هُو الطُّهُورُ الَّذِي تَطَّهَّرُونَ بِهِ؟» قَالُوا يَا رَسُولَ اللهِ مَا نَعْلَمُ شَيْئًا إِلَّا أَنَّه كَان لَنَا جِيرَانٌ مِن الْيَهُودِ فَكَانُوا يَغْسِلُونَ أَدْبَارَهُمْ مِنَ الْغَائِطِ فَغَسَلْنَا كَمَا غَسَلُوا
