Whenever Allah reveals something it means the people and Jinn of this world have earned it and Allah, through His Wali, is teaching His Mala’ikah what that thing looks like so it is properly defined in front of them and they can identify it and its people.
Allah revealed to us the criteria for entering the lowest level of the lowest depth of hell, this is a place is reserved for the lowest of low, the absolute worst in Allah’s creation.
They will receive their punishment from Isim Allah Al Azzim, Allah’s greatest name, His highest name that is most complete and so their punishment will be the most complete in every respect.
This is being revealed in our lifetime because the people of our lifetime deserve it, it is in our life time the world saw the worst oppression in its history, the fitnah of the Dajjal (Allah’s curse be upon him) will be the worst fitnah because it will drag people to Kufr, but in terms of actual oppression, what is happening now won’t be repeated again because between us and the Dajjal is Imam Mahdi (ra) who will spread justice as this oppression was spread and the light of that on earth means people will not reach the same standards of degeneracy or depravity again.
The Prophet (saws) said about his Fitnah: “Severe calamity from the direction of their ruler (Saddam Hussein) will befall my people during the Last Days (this is its start, the beginning of Kufar entering Islamic lands, it will continue for decades after Him). It will be a calamity which, in severity, shall be unprecedented (in earth’s history). It will be so violent that the earth with injustice and corruption (it will entirely be covered by these) will shrivel (become small) for its inhabitants (they will have no place to go because this fitnah will cover the entire world). The believers will not find refuge from oppression. At that time (this is relatively speaking, when it will end decades later) Allah will send a man from my family to fill the earth with justice (The fitnah began with Saddam but the oppression began on September the 11th and it will end when Imam Mahdi (as) appears to reverse it. This hadith is part of a number of other ahadith which is how we know the ruler is Saddam Hussein and what this is referring to)” (Ibn Hajar)
Allah in the Quran describes the people of the lowest hell as firewood for the fire, the people of the lowest depth in their punishment will be like firewood at its most hottest when all moisture is taken from the wood and it begins to crackle and then snap because of the heat, this is the description given to us by Rasul Allah (saws).
Consider this, the prophets Uncle Abu Lahab who an entire surah was revealed about Him and His wife calling him Abu Lahab, the father of (all) burning, will be released from punishment on Monday because He celebrated the Mawlid of Rasul Allah (saws).
The relentlessness of the punishment of these people by comparison will be far worse than him, it will not stop, it will be relentless and at speed, continuous, like something rushing to cover them entirely at every second and micro second of their existence.
We know this because this is the reality of Allah’s Ghawth (Helpers): Al-Harith ibn Malik al-Ansari (some chains have: al-Haritha ibn al-Na`man al-Ansari): He passed by the Prophet who asked him: “How are you this morning O Haritha?” He replied: “This morning I am a real believer.” The Prophet said: “Take care of what you say: what is the reality of your belief?” He said: “I have turned myself away from this world by keeping awake at night and by keeping myself thirsty by day; and I can almost see the Throne of my Lord in full sight; and I can see the people of the Garden of Paradise visiting each other; and I can almost see the people of the Fire wailing to each other in it (As if the Arsh, Heaven and Hell are on earth).” The Prophet said: “O Haritha, you do know: therefore cleave to it.” Some versions add: “This is a believer, Allah has illumined his heart” (mu’minun nawwara Allahu qalbah).
The people and Jinn who will earn this punishment from Allah, and once this was revealed to us by Allah the Mala’ikah left and identified all its people and Jinn the majority of whom are in our life time, are the people who in this life where relentless in chasing after the Muslims every day, hour and second of their lives in order to make them Kufar, Rasul Allah (saws) mentions their work in Ahadith:
Abu Hurairah said, The Prophet said, Woe to the Arabs from the great evil which is nearly approaching them: it will be like patches of dark night. A man will wake up as a believer, and be a kafir (unbeliever) by nightfall. People will sell their religion for a small amount of worldly goods. The one who clings to his religion on that day will be as one who is grasping an ember – or thorns. (Ahmad.)
Its people are the people responsible for this fitnah, their Jinn are predators always on the prowl hunting Muslims down, whenever they see an opening in their nafs they interject themselves therein, they continuously keep doing this until they cover the person entirely, and if they are ever defeated they return with others of their kind, with Jinn and help from their masters.
They chase after people with sihr surrounding Muslims from all sides so their spirituality comes only from under the control of their sihr and they block anything else from reaching them, from Allah, His Mala‘ikah or Ahl Al Ghayb, they deconstruct their lives, work, families and destroy them from the inside out from places within them beyond their capacity to perceive, so they leave Islam.
If a Muslim finds a way to defeat them they continue to chase them to the ends of the earth so a Muslim finds no place safe, again Rasul Allah (saws) mentioned this in Ahadith, they are relentless in their effort so Allah’s punishment will match theirs, Allah wrote this in the universe that every act will be repaid in kind, like for like:
“And We ordained for them therein a life for a life, an eye for an eye, a nose for a nose, an ear for an ear, a tooth for a tooth, and for wounds is legal retribution.” (5:45)
You took pride in your relentlessness this is the punishment your actions created for you, had you minds that had foresight.
I am fulfilling my obligation to Rasul Allah (saws) in passing on His (saws) advice regarding this, He (saws) said: “Who ever wants freedom from this punishment, should move away from performing these actions”.
This is the nature of this life, it is not to late to free yourself from this fate/akhira, because these people for them Jahanam is eternal, they will not be released from it…death is the only thing that makes fate final, so stop what you are doing and leave these people.
