Abu Hurairah (May Allah be pleased with him) reported: We were in the company of Messenger of Allah (ﷺ) when we heard a bang. Thereupon Messenger of Allah (ﷺ) said. "Do you know what this (sound) is?" We said, "Allah and His Messenger know better." He (ﷺ) said, "That is a stone which was thrown into Hell seventy years before and it has just reached its bottom". [Muslim] .
