What did the Prophet Muhammad (saw) say about the depth of Hell?
 It is narrated on the authority of Abu Huraira and Hudhaifa that the Messenger of Allah (may peace be upon him) said:                      Allah, the Blessed and Exalted, would gather people. The believers would stand till the Paradise would be brought near them. They would come to Adam and say: O our father, open for us the Paradise. He would say: What turned ye out from the Paradise was the sin of your father Adam. I am not in a position to do that; better go to my son Ibrahim, the Friend of Allah. He (the Holy Prophet) said: He (Ibrahim) would say: I am not in a position to do that. Verily I had been the Friend (of Allah) from beyond, beyond; you better approach Moses (peace be upon him) with whom Allah conversed. They would come to Moses (peace be upon him), but he would say: I am not in a position to do that; you better go to Jesus, the Word of Allah and His Spirit. Jesus (peace be upon him) would say: I am not in a position to do that. So they would come to Mubammad (may peace be upon him). He would then be permitted (to open the door of Paradise). Trust worthiness and kinship would be despatched, and these would stand on the right and left of the Path and the first of you would pass with (the swiftness) of lightning. He (the narrator) said: I said, O thou who art far dearer to me than my father and my mother I which thing is like the passing of lightning? He said: Have you not seen lightning, how it passes and then comes back within the twinkling of an eye? Then (they would pass) like the passing of the wind, then like the passing of a bird, and the hastening of persons would be according to their deeds, and your Apostle would be standing on the Path saying: Save, O my Lord, save. (The people would go on passing) till the deeds of the servants would be failing in strength, till a man would come who would find it hard to go along (that Path) but crawlingly. He (the narrator) said: And on the sides of the Path hooks would be suspended ready to catch anyone whom these would be required (to catch). There would be those who would somehow or other succeed in trasversing that Path and some would be piled up in Hell. By Him in Whose Hand is the life of Abu Huraira it would take one seventy years to fathom the depth of Hell.
