[Quranic Reflection]: the sound of hell.

[Angrboda]

Black Holes are "scorching hot" on the outside but freezing cold in the inside:

The more massive a black hole, the colder it is.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius.
Supermassive black holes are even colder.
But a black hole's event horizon is incredibly hot. The gas being pulled rapidly into a black hole can reach millions of degrees.

Matching this description of hell from the Quran:

Sura 11, The Quran:
https://quran.com/11?startingVerse=106

(106) As for those bound for misery, they will be in the Fire, where they will be sighing and gasping,
(107) staying there forever, as long as the heavens and the earth will endure, except what your Lord wills.1 Surely your Lord does what He intends.

The sighing and gasping of hell are the cold & heat.

Fire is rapid oxidation. The phenomenon at the surface of a black hole is not rapid oxidation and is not fire. Therefore it doesn't match the description.

Just because fire is hot doesn't mean that all things that are hot are like fire.
