Beginning of Creation
The description of the (Hell) Fire and the fact that it has already been created
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 .
Narrated Ibn `Umar: The Prophet (ﷺ) said, "Fever is from the heat of the (Hell) Fire; so abate fever with water."
