it was narrated on the authority of yazdgerd bin shahriyar the last of the persian kings that he sent a messenger to omar bin alkhattab may god be pleased with him and ordered him to look at his features. when he entered the city he said where is your king? they said we have no king we have a prince. he went out by land. the man went after him and found him sleeping in the sun his cloak under his head and his side was sweating until the ground was wet from it. when he saw him in his condition he said i was just and felt safe so i slept and our friend was a neighbor so he was afraid and stayed awake. i bear witness that the religion is your religion and if i were not a messenger i would have converted to islam and i will return god almighty willing.
وقد حكى عن يزدجرد بن شهريار آخر ملوك العجم أنه بعث رسولا الى عمر بن الخطاب رضى الله عنه وأمره أن ينظر في شمائله فلما دخل المدينة قال أين ملككم قالوا ليس لنا ملك لنا أمير خرج برا فخرج الرجل في أثره فوجده نائما في الشمس ودرته تحت راسه وقد عرق جنبه حتى ابتلت منه الأرض فلما رآه على حالته قال عدلت فأمنت فنمت وصاحبنا جار فخاف فسهر أشهد أن الدين دينكم ولولا أني رسول لأسلمت وسأعود بإذن الله تعالى
