Musannaf Ibn Abi Shaybah 39387 — Reports on the letters of the Prophet

It is narrated from Abdullah bin Shaddad that Kisra wrote to Badham: I have been informed that a man is saying something that I do not know. So send someone to him, so that he may sit quietly in his house and not spread anything among the people; otherwise, let him fix a time and place with me and I will meet him there. The narrator said: Badham sent to the Messenger of Allah (peace and blessings be upon him) two men with shaved beards and long moustaches. The Messenger of Allah (peace and blessings be upon him) said: What has driven you to this? The narrator said: The two of them said to him (peace and blessings be upon him): We have been ordered to do this by the one who, as people claim, is their Lord. The narrator said: The Messenger of Allah (peace and blessings be upon him) said: But we go against your way. We clip this (the moustache) and we let this (the beard) grow. The narrator said: A man of Quraysh with long moustaches passed by him (peace and blessings be upon him), and he (peace and blessings be upon him) ordered him to clip them. The narrator said: He (peace and blessings be upon him) left those envoys for twenty-odd days. Then he (peace and blessings be upon him) said: Go to the one whom you claim to be your Lord, and tell him that my Lord has killed the one who claimed to be a lord. The men asked: When did this happen? He (peace and blessings be upon him) said: Today. The narrator said: The two went to Badham and gave him this news. The narrator said: He wrote to Kisra, and they found that the killing of Kisra had taken place on that very day.
