Musnad Abu Ya'la al-Mawsili 161:22

Narrated to us Ishaq, narrated to us Abu Ubaydah, narrated to us Hisham bin Hassan, from Muhammad—he is Ibn Shabib—from Ja'far bin Abi Wahshiyah, from Sa'id bin Jubayr, from Abu Hurayrah, from the Prophet (peace be upon him), who said: "If there were in this mosque a hundred or more, and among them was a man from the people of the Fire, and he breathed and it reached himself, the mosque and whoever is in it would burn."
