وَ بِهَذَا اَلْإِسْنَادِ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ حَدِيدٍ وَ اِبْنِ أَبِي نَجْرَانَ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزِ بْنِ عَبْدِ اَللَّهِ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ:« جَرَتِ اَلسُّنَّةُ فِي أَثَرِ اَلْغَائِطِ بِثَلاَثَةِ أَحْجَارٍ أَنْ يَمْسَحَ اَلْعِجَانَ وَ لاَ يَغْسِلَهُ وَ يَجُوزُ أَنْ يَمْسَحَ رِجْلَيْهِ وَ لاَ يَغْسِلَهُمَا».
And through this chain of narration, from Ahmad bin Muhammad, from Ali bin Hadeed and Ibn Abi Najran, from Hammad bin Isa, from Hariz bin Abdullah, from Zurara, from Abu Ja'far عليه السلام, who said:
Imam عليه السلام said: 'It is the established practice that after defecation, one wipes with three stones to clean the perineum and does not wash it. It is also permissible to wipe the feet and not wash them.'
