Abu Huraira reported:We were in the company of Allah's Messenger (ﷺ) that we heard a terrible sound. Thereupon Allah's Apostle (ﷺ) said: Do you know what (sound) is this? We said: Allah and His Messenger know best. Thereupon he said: That is a stone which was thrown seventy years before in Hell and it has'been constantly slipping down and now it has reached its base

This hadith has been narrated on the authority of Abfi Huraira with the same chain of transmitters but with this change of wording that the Prophet (may. peace be upon him) said:It reached at its base and you heard its sound
