وَ بِهَذَا اَلْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ بْنِ يَحْيَى عَنْ عَلِيِّ بْنِ اَلسِّنْدِيِّ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ حَرِيزٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ:« يَغْسِلُ اَلرَّجُلُ يَدَهُ مِنَ اَلنَّوْمِ مَرَّةً وَ مِنَ اَلْغَائِطِ وَ اَلْبَوْلِ مَرَّتَيْنِ وَ مِنَ اَلْجَنَابَةِ ثَلاَثاً».
And through this chain of narration, from Muhammad bin Ahmad bin Yahya, from Ali bin Al-Sindi, from Hammad bin Isa, from Hariz, from Abu Ja'far عليه السلام, who said:
Imam عليه السلام said: 'A man washes his hand once after sleep, twice after defecation or urination, and three times after janabah (major ritual impurity).'
