Did Imam Muhammad ibn Abd al-Wahhab say that Hellfire would cease to exist?

Imam Muhammad ibn Abd al-Wahhab did not assert the annihilation of Hellfire; rather, what is established from him is the statement that it will not perish. He mentioned in his personal letters to the people of Qassim that he believes Paradise and Hell are created and exist today, and they will not cease to be. Sheikh Salih al-Fawzan affirmed that Paradise and Hell will never perish eternally, and that the persistence of a creation is due to Allah Almighty sustaining it. This refutes those who claim the annihilation of Paradise and Hell, or the annihilation of Hell without Paradise.
