 it is the right of the king not to laugh at his speech when he speaks because laughing in the presence of the king is an audacity towards him and one should not show astonishment at the benefit of his speech. this is up to the king. if the king laughs at the speech and shows pleasure at it then that is the purpose of his speech and that is what he intended. if he is silent and there is nothing in the speech that would distract him or make him happy or benefit from it then he has been free from fault since he did not laugh or show astonishment.
ومن حق الملك أن لا يضحك من حديثه إذا حدث، لأن الضحك بحضرة الملك جرأة عليه؛ ولا يظهر التعجب بفائدة حديثه. وإنما هذا إلى الملك. فإن ضحك الملك من الحديث، وأظهر السرور به، فذاك غرض حديثه، وإليه قصد؛ وإن سكت، فلم يكن في الحديث ما يلهيه ويطر به أو يستفيد منه فائدة، كان قد سلم من العيب، إذ لم يضحك ولم يعجب.
