It is narrated from the same chain that I heard Abul Qasim (peace be upon him) say: "This fire of yours which the children of Adam kindle is one part out of seventy parts of the fire of Hell." The noble companions (may Allah be pleased with them) said, "O Messenger of Allah! By Allah, even this one part is sufficient." The Prophet (peace be upon him) said, "The fire of Hell is sixty-nine degrees hotter than this, and each degree is like the heat of this (worldly fire)."
