مَا أَخْبَرَنِي بِهِ اَلشَّيْخُ أَيَّدَهُ اَللَّهُ تَعَالَى قَالَ أَخْبَرَنِي أَحْمَدُ بْنُ مُحَمَّدِ بْنِ اَلْحَسَنِ عَنْ أَبِيهِ عَنْ مُحَمَّدِ بْنِ اَلْحَسَنِ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَاَلْحُسَيْنِ بْنِ اَلْحَسَنِ بْنِ أَبَانٍ عَنِ اَلْحُسَيْنِ بْنِ سَعِيدٍ عَنْ عُثْمَانَ عَنْ سَمَاعَةَ قَالَ: سَأَلْتُهُ عَنِ اَلْمَاءِ اَلْجَارِي يُبَالُ فِيهِ قَالَ« لاَ بَأْسَ».
Narrated to me by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, who said: Ahmad bin Muhammad bin Al-Hasan narrated to me, from his father, from Muhammad bin Al-Hasan, from Ahmad bin Muhammad and Al-Husayn bin Al-Hasan bin Aban, from Al-Husayn bin Sa'id, from Uthman, from Sama'ah, who said:
I asked Imam عليه السلام about urinating in running water. Imam عليه السلام said: 'There is no harm in it.'
