When Prophet Adam was revealed to earth, he no longer obtained food easily as in heaven. He must work hard to get fruits or meat to eat. When he obtained hunted animals and slaughtered them, it turned out that he could not immediately be eaten just because it was raw and certainly not tasty. Therefore he prayed to Allah to bring down fire for cooking.
So Allah SWT sent the Angel Gabriel asking for a little fire to the Angel Malik in hell, for the purpose of the Prophet Adam. Malik said, "O Gabriel, how much do you want fire?"
****Gabriel said, "I want the fire of hell the size of a date palm !!"****
Malik said, "If I give hellfire the size of a date palm, then the seven heavens and the entire earth will melt because of the heat !!"
****Jibril said, "Then just give me half the dates****
Malik said again, "If I give what you want, then the sky will not drop a drop of rain, and all the water on the earth will dry up so that no plants will live !!"
The angel Gabriel became confused, how much hell's fire was 'safe' for life on earth ?? Therefore he prayed, "O God, how much hell do I have to take for Adam's needs on earth ??"
Allah said, "Bring fire from hell as big as zarrah (the smallest unit, atom) !!"
So Jibril asked Hell for fire as much as zarrah and brought it to earth. But upon arrival on earth, Gabriel felt the fire as big as the zarrah was still too hot, so he dipped (washed it) seventy times into seventy different rivers. Only then did he bring it to Prophet Adam, and put it on a high mountain.
But once the fire was laid, the mountain fell apart. Soil, rocks, iron and everything around the fire become very hot coals, and emit smoke. Even the fire that was as big as the zarah continued to penetrate the earth, and that made Jibril worry. Therefore he immediately took the fire and brought it back to hell. The burning coals left behind have been the source of world fire, including those that have become magmas in all the volcanoes on this earth.
You can't imagine how hot the fire is. If the fire coals of the world are generally red, then the coals of hellfire are dark black, like dark black at night. The Prophet SAW once asked about the state of hell's fire, so the Angel Gabriel said, "Indeed Allah SWT created hell, then lit the fire of hell for a thousand years so that (the new) is red. Then (Allah) turns it on (adds heat) for another thousand years so that (the bar) is white, and (He) turns it on (adds heat) for another thousand years so that (it is) black. Then hell is dark black like the black night which is very dark, never calm the flames and never goes out (decreases) the fire !! ”
