Hadith 1146أَحْمَدُ عَنْ أَبِيهِ عَنْ سُلَيْمَانَ الْجَعْفَرِيِّ قَالَ قَالَ أَبُو الْحَسَنِ ( عليه السلام ) رُبَّمَا أُتِيَ بِالْمَائِدَةِ فَأَرَادَ بَعْضُ الْقَوْمِ أَنْ يَغْسِلَ يَدَهُ فَيَقُولُ مَنْ كَانَتْ يَدُهُ نَظِيفَةً فَلَا بَأْسَ أَنْ يَأْكُلَ مِنْ غَيْرِ أَنْ يَغْسِلَ يَدَهُ .
13. Ahmad has narrated from his father from Sulayman al-Ja‘fariy who has said the following: “Abu al-Hassan (a.s.), when food was made available and certain people had not washed their hands, would say, ‘Those whose hands are clean can eat without washing their hands.’”
