I want to understand the concept of hell fire. Why does it exist? From my understanding, Allah SWT is All-Just, but Mercy is greater than his Justice, meaning he may choose to forgive those who deserve to be punished. I know that most deserve to be punished for their sins, and that not many stay in hell forever, but my question is about the severity of hell, why such a painful punishment? When I imagine what hell holds for the transgressors I feel like it's unbearable, but I know for a fact that whatever I can imagine is nothing compared to the actual punishment, so why such a painful punishment for the disbelievers? What I mean is, I know Allah SWT only gives the disbelievers what they truly deserve, but I can't fathom how they deserve a punishment so severe. Please help me further understand the concept of hell.
