Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 15
سَهْلُ بْنُ زِيَادٍ عَنْ مُوسَى بْنِ اَلْقَاسِمِ عَنْ عَمْرِو بْنِ سَعِيدٍ عَنْ مُصَدِّقِ بْنِ صَدَقَةَ عَنْ عَمَّارٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ اَلرَّجُلُ يُرِيدُ أَنْ يَسْتَنْجِيَ كَيْفَ يَقْعُدُ قَالَ« كَمَا يَقْعُدُ لِلْغَائِطِ» وَ قَالَ« إِنَّمَا عَلَيْهِ أَنْ يَغْسِلَ مَا ظَهَرَ مِنْهُ وَ لَيْسَ عَلَيْهِ أَنْ يَغْسِلَ بَاطِنَهُ».
Sahl ibn Ziyad, from Musa ibn al-Qasim, from Amr ibn Sa'id, from Musaddiq ibn Sadaqah, from Ammar, from Abu Abdullah عليه السلام, said:
I asked Imam عليه السلام: "How should a man sit when he wants to perform istinja (cleaning after relieving oneself)?" Imam عليه السلام replied: "He should sit as he sits for relieving himself." And Imam عليه السلام said: "He is only required to wash the part that is visible and is not required to wash the inner part."
