He [the Governor of Fars] received Him with the utmost insolence and bade Him occupy a seat facing him in the centre of the room. He publicly rebuked Him, and in abusive language denounced His conduct. “Do you realise,” he angrily protested, “what a great mischief you have kindled? Are you aware what a disgrace you have become to the holy Faith of Islám and to the august person of our sovereign? Are you not the man who claims to be the author of a new revelation which annuls the sacred precepts of the Qur’án?” The Báb calmly replied: “‘If any bad man come unto you with news, clear up the matter at once, lest through ignorance ye harm others, and be speedily constrained to repent of what ye have done.’” These words inflamed the wrath of Husayn Khán. “What!” he exclaimed. “Dare you ascribe to us evil, ignorance, and folly?” Turning to his attendant, he bade him strike the Báb in the face. So violent was the blow, that the Báb’s turban fell to the ground.
