باب صِفَةِ النَّارِ وَأَنَّهَا مَخْلُوقَةٌ

حَدَّثَنَا مُسَدَّدٌ، عَنْ يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَأَبْرِدُوهَا بِالْمَاءِ ‏"‏‏.‏

The Prophet (ﷺ) said, "Fever is from the heat of the (Hell) Fire; so abate fever with water."
