Question 252: Is it true that the fire we use in cooking is the smoke of the fire of Hell (may Allaah protect us from it)?
Answer: This is not true. Yet, the Prophet (peace be upon him) said, When it is intensely hot, then wait until it cools down before you pray, for intense heat is from the intensity of the heat of Hell. (Narrated by Al-Bukhaaree, Muslim and the Compilers of the Sunan [‘Aboo Daawood, Ibn Majah, Al-Tirmidee and Al-Nasaa’ee]) Moreover, the Prophet (peace be upon him) said, “This (worldly) fire of yours which you use is one of seventy parts of the Hell.” They said, “O Messenger of Allaah! It (the fire of this world) would have been sufficient (as a punishment).” He said, “It (Hell-fire) is made to surpass (worldly fire) by sixty-nine parts, each of them is as hot.” (Narrated by Al-Bukhaaree)... read more here.
