Sheikh `Umar al-Muqbil, professor at al-Imâm University
The hadîth that the Prophet (peace be upon him) saw a woman hanging in the Hellfire by her hair was cited in a narration allegedly by `Ali b. Abî Tâlib from the Prophet (peace be upon him). It is a long hadîth depicting many frightening and horrible things.
However, it is a false hadîth concocted and disseminated by some ignorant people in order to frighten women. It is unlawful to fabricate hadîth and to lie to frighten people.
The eminent scholar Sheikh Bin Bâz has already issued a verdict on the falseness of this hadîth [Verdict No. 19493].
