 for some reason when the kings of the sassanid dynasty were served their tables they would mumble over them and no one would utter a word until they were removed. if they were forced to speak they would use gestures and signs to indicate the purpose they wanted and the meaning they intended.
ولشيء ما، كانت ملوك آل ساسان، إذا قدمت موائدهم، زمزموا عليها، فلم ينطق ناطق بحرف حتى ترفع. فإن اضطروا إلى كلام، كان مكانه إشارة وإيماء يدل على الغرض الذي أرادوا، والمعنى الذي قصدوا.
