 it is the right of the king that no one should raise his voice in his presence because lowering voices in his presence is a sign of respect and reverence for the king as this is more in his splendor glory and authority.
ومن حق الملك أن لايرفع أحد صوته بحضرته، لأن من تعظيم الملك وتبجيله، خفض الأصوات بحضرته، إذ كان ذلك أكثر في بهائه وعزه وسلطانه.
