أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ عَنِ اَلْحُسَيْنِ عَنْ مُوسَى بْنِ سَعْدَانَ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ قَالَ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ:« لاَ يُجْنِبُ اَلْأَنْفُ وَ اَلْفَمُ لِأَنَّهُمَا سَائِلاَنِ».
Narrated by Ahmad ibn Muhammad, from Muhammad ibn al-Husayn, from al-Husayn, from Musa ibn Sa'dan, from Abdullah ibn Sinan, who said:
Abu Abdullah عليه السلام said: "The nose and mouth do not become junub (affected by the state of major ritual impurity) because they are passageways (sa’ilan)."
