Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) relates that Bunnah al-Juhani (may Allah be pleased with him) told him that the Prophet of Allah (peace and blessings be upon him) passed by some people in a mosque who had drawn a sword from its sheath in it and were passing it to one another. So he (peace and blessings be upon him) said: "May Allah curse whoever does this! Did I not forbid you from it? When one of you draws a sword, let him sheathe it, then hand it to his companion in that way."
Ka'b (al-Ahbar) relates: "Ammuriyah is the bitch of Constantinople, because it barks in front of it."
