لَوْ كَانَ فِي هَذَا الْمَسْجِدِ مِائَةُ [أَلْفٍ] أَوْ يَزِيْدُوْنَ، وَفِيْهِ رَجُلٌ مِنْ أَهْلِ النَّارِ فَتَنَفَّسَ فَأَصَابَهُمْ نَفَسُهُ لَاحْتَرَقَ الْمَسْجِدُ وَمَنْ فِيْهِ

Abu Hurairah, may Allaah be pleased with him, said, “The Prophet of Allaah صلى الله عليه وسلم said, ‘If there were a hundred (thousand) or more in this mosque, and in it was a man from the People of the Fire who took a breath and whose breath came upon them, the mosque and those in it would burn.’”
