In Al-Fiqh al-Akbar, Abu Hanifa (May Allah have mercy on him) said: "Believing that Hell will cease to exist-the torment of the Kaafireen (Disbelievers) won`t last forever-is Kufr (Disbelief)." I have also read this in several books of Shafi, Maliki, Hanafi, and other scholars, although some of them have books indicating that Hell will never end and the Kaafireen will be tormented there forever, as supported by a great deal of evidence from the Quran and the Prophetic Sunnah. As far as I know, this is by `ijma`(Consensus) of the scholars. However, a few days ago, I read a book where it was stated that Hell will cease to exist and the torment of the Kaafireen won`t last forever. There is also a view that these Kaafireen will eventually be admitted to Jannah (Paradise). This view felt so strange to me. Is it permissible for a Muslim to believe that Hell will cease to exist? Is saying so considered Kufr or going astray? What is the ruling of Sharia on this?
