In one of His talks to the friends in Haifa, Abdu'l-Baha is reported to have said that Jamal was so proud that he did not allow the believers to sit in his presence. In order to show their respect, they had to stand to hear him speak. Once, an old man who was not a believer had come to one of his meetings to investigate the Faith. When he saw everyone was standing, he had to obtain special permission from Jamal to sit down, for he was an old person and could not stand on his feet for long. Abdu'l-Baha said that it was a good thing that Jamal was finally expelled, as he was like unto a poison to the Baha'i community.
