Muhammad Ibn Ali ­Shalmaghani Azaqari challenged Shaykh Husain Ibn Rauh to a Mubahila (imprecation contest), saying, “I am the companion of the Imam and have been ordered to manifest my knowledge, which I have manifested expressly and implicitly; so come to my Mubahila.” The Shaykh replied, “Whoever of us dies first, is the one who bears the anathema.” Azaqari died first, as he was killed, crucified and Ibn Abi Aun was taken with him. This was in the year three hundred and thirteen.
