Chapter: Al-Qaâimâs aspects and deeds (14) Abdul Wahid bin Abdullah bin Younus narrated from Ahmad bin Muhammad bin Rabah from Ahmad bin Ali al-Himyari from al-Hasan bin Ayyoob from Abdul Kareem bin Amr from Ahmad bin al-Hasan bin Abban that Abdullah bin Attaâ al-Mekki had asked Abu Abdullah as-Sadiq (as) about the conduct of Imam al-Mahdi (aj) when he would appear. Abu Abdullah as-Sadiq (as) said: âHe will act as the Prophet (S) has acted.
He will annul all what has been established before him as the Prophet (S) has annulled all that has been established in the pre-Islamic age. He will resume Islam anew.â
