One of the Kisrás sent a confidential messenger to Máhiya-sar ordering him to present himself at his court, under pain of incurring the Royal displeasure, Máhiya-sar had prepared a talisman which kept all the frogs and other reptiles (<Arabic>) quiet during the day, but at night they made so much noise that the whole heaven and earth seemed to be in commotion. When at night-time Kisrá’s ambassador heard this fearful riot (<Arabic>), he was dazed with wonder and fear, and asked what was the matter. They replied, “The king’s watchmen by night.” “And where,” enquired he, “are they by day?” “By day,” they answered, “they rest.” When the ambassador returned and related this to Kisrá, they told him that he must have been dreaming.

In the History of the Barmecides (<Arabic>) it is said that this Máhiya-sar originally owned the “Barmecide Ring” (<Arabic>) which afterwards belonged to the Umayyad Caliph 'Abdu`l-Malik b. Marwán (A. D. 685—705); but this story, as well as many others referring to Máhiya-sar which are given by al-Yazdádi, is discredited by the author on chronological grounds.
