Mukhtasar Bukhari

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The heat of your fire is one part out of seventy parts of the heat of the Fire of Hell." It was said, "O Messenger of Allah! The fire of this world would have been sufficient for burning." He (peace and blessings of Allah be upon him) said: "It has been increased by sixty-nine parts, each part as hot as it."
