then he appointed a spy to him to prepare his message and write down his words. when the messenger returned the message the spy would bring what he had written of his words and answers. the king would compare them with the messengers words. if they agreed or their meanings agreed the king would know that he was sound in mind and that his speech was true. then the king would appoint him as a messenger to his enemy and appoint a spy to memorize his words and write them down then he would submit them to the king. if the messengers words agreed with the kings spy and he would know that his messenger had told him the truth about his enemy and had not gone too far because of the enmity between them he would appoint him as his messenger to the kings of the nations and trust him. then after that he would establish his report as evidence.
ثم تقدم عينا عليه، يحضر رسالته ويكتب كلامه. فإذا رجع الرسول الرسالة، جاء العين بما كتب من ألفاظه وأجوبته. فقابل بها الملك ألفاظ الرسول. فإن اتفقت أو اتفقت معانيها، عرف الملك صحة عقله، وصدق لهجته، ثم جعله الملك رسولا إلى عدوه، وجعل عليه عينا يحفظ ألفاظه ويكتبها، ثم يرفعها إلى الملك. فإن اتفق كلام الرسول وكلام عين الملك، وعلم أن رسوله قد صدقه عن عدوه ولم يتزيد عليه للعداوة بينهما، جعله رسوله إلى ملوك الأمم، ووثق به. ثم كان بعد ذلك يقيم خبره مقام الحجة.
