Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 12
مَا أَخْبَرَنِي بِهِ اَلشَّيْخُ أَيَّدَهُ اَللَّهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنِ اَلْحُسَيْنِ بْنِ اَلْحَسَنِ بْنِ أَبَانٍ عَنِ اَلْحُسَيْنِ بْنِ سَعِيدٍ عَنِ اَلْقَاسِمِ عَنْ عَلِيٍّ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: فِي مُصَافَحَةِ اَلْمُسْلِمِ لِلْيَهُودِيِّ وَ اَلنَّصْرَانِيِّ قَالَ« مِنْ وَرَاءِ اَلثِّيَابِ فَإِنْ صَافَحَكَ بِيَدِهِ فَاغْسِلْ يَدَكَ».
The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from Al-Husayn ibn Al-Hasan ibn Aban, from Al-Husayn ibn Sa'id, from Al-Qasim, from Ali, from Abu Basir, from Abu Ja'far عليه السلام.
Imam عليه السلام said regarding the handshaking of a Muslim with a Jew or a Christian: "Shake hands with them through a cloth. But if he shakes your hand directly, then wash your hand."
