A fire Hamiyah!
meaning, extreme heat. It is a heat that is accompanied by a strong flame and fire.
It is narrated from Abu Hurayrah that the Prophet said,
نَارُ بَنِي ادَمَ الَّتِي تُوقِدُونَ جُزْءٌ مِنْ سَبْعِينَ جُزْءًا مِنْ نَارِ جَهَنَّم
The fire of the Children of Adam that you all kindle is one part of the seventy parts of the fire of Hell.
They (the Companions) said, "O Messenger of Allah! Isn't it sufficient"
He replied,
إِنَّهَا فُضِّلَتْ عَلَيْهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا
It is more than it by sixty-nine times.
This has been recorded by Al-Bukhari and Muslim. In some of the wordings he stated,
إِنَّهَا فُضِّلَتْ عَلَيْهَا بِتِسْعَةٍ وَسِتِّينَ جُزْءًا كُلُّهُنَّ مِثْلُ حَرِّهَا
It is more than it by sixty-nine times, each of them is like the heat of it.
It has been narrated in a Hadith that Imam Ahmad recorded from Abu Hurayrah that the Prophet said,
إِنَّ أَهْوَنَ أَهْلِ النَّارِ عَذَابًا مَنْ لَهُ نَعْلَنِ يَغْلِي مِنْهُمَا دِمَاغُه
Verily, the person who will receive the lightest torment of the people of the Hellfire will be a man who will have two sandals that will cause his brain to boil.'
It has been confirmed in the Two Sahihs that the Messenger of Allah said,
اشْتَكَتِ النَّارُ إِلَى رَبِّهَا فَقَالَتْ
يَا رَبِّ أَكَلَ بَعْضِي بَعْضًا
فَأَذِنَ لَهَا بِنَفَسَيْنِ
نَفَسٍ فِي الشِّتَاءِ وَنَفَسٍ فِي الصَّيْفِ
فَأَشَدُّ مَا تَجِدُونَ فِي الشِّتَاءِ مِنْ بَرْدِهَا وَأَشَدُّ مَا تَجِدُونَ فِي الصَّيْفِ مِنْ حَرِّهَا
The Hellfire complained to its Lord and said,
"O Lord! Some parts of me devour other parts of me."
So He (Allah) permitted it to take two breaths;
- one breath in the winter and
- one breath in the summer.
Thus, the most severe cold that you experience in the winter is from its cold, and the most severe heat that you experience in the summer is from its heat.
In the Two Sahihs it is recorded that he said,
إِذَا اشْتَدَّ الْحَرُّ فَأَبْرِدُوا عَنِ الصَّلَةِ فَإِنَّ شِدَّةَ الْحَرِّ مِنْ فَيْحِ جَهَنَّم
When the heat becomes intense pray the prayer when it cools down, for indeed the intense heat is from the breath of Hell.
This is the end of the Tafsir of Surah Al-Qari`ah, and all praise and thanks are due to Allah
