What is the length of Paradise, and where are Hellfire and its length located, given that the width of Paradise encompasses the heavens and the earth?

It has been established in revelation that the width of Paradise is known, but its length is known only to Allah. This is among the unseen matters, the knowledge of which is impossible except through revelation, and no statement regarding its length has been mentioned in revelation.

As for Hellfire, it is also among the unseen matters, and we do not know of any text regarding its exact dimensions in length and width. However, it has been established that its depth downwards is a distance of seventy years.
