[Machine] They said to Salman, "Did your Prophet ﷺ teach you everything, even how to clean yourselves after using the bathroom?" He replied, "Yes, indeed. He forbade us from facing the qibla (direction of prayer) while defecating or urinating. He also prohibited us from performing istinja (cleansing after using the bathroom) with less than three stones. And he forbade us from using dung or bones for istinja."
قَالُوا لِسَلْمَانَ قَدْ عَلَّمَكُمْ نَبِيُّكُمْ ﷺ كُلَّ شَيْءٍ حَتَّى الْخِرَاءَةَ؟ فَقَالَ أَجَلْ قَدْ نَهَانَا أَنْ نَسْتَقْبِلَ الْقِبْلَةَ بِغَائِطٍ أَوْ بَوْلٍ وَنَهَانَا أَنْ يَسْتَنْجِيَ أَحَدُنَا بِأَقَلَّ مِنْ ثَلَاثَةِ أَحْجَارٍ وَنَهَانَا أَنْ نَسْتَنْجِيَ بِرَجِيعٍ أَوْ بِعَظْمٍ
