He (Ibn Sad) said: 'Ali Ibn Muhammad informed us on the authority of Amr Ibn Abd al-Rahman al-Zuhri, he on the authority of Zamil Ibn Amr al-Judhami; he said:
Farwah Ibn ‘Amr al-Judhuami was the Roman ‘amil of ‘Amman, a
territory of al-Balga or on Mu’àn. He embraced Islam and wrote to the
Apostle of Allah, may Allah bless him, about his conversion to Islam and
sent the message through a man of his tribe whose name was Mas’ud Ibn
Sad. He also sent with him a white mule, a horse, an ass, soft clothes, and a qabá of sarsenet embroidered with gold. Thereupon the Apostle of Allah, may Allah bless him, wrote to him: From Muhammad the Apostle of Allah to Farwah Ibn 'Amr: After that, your messenger came to us and delivered what you had despatched and gave information relating to you. He mentioned that you have embraced Islam and that Allah has guided you in His guidance; so do good deeds, obey Allah and His Apostle, offer prayers and pay zakah. He (Prophet) commanded Bilàl who made a gift of twelve and half ounces (silver) to his (Farwah's) messenger, Mas'ud Ibn Sad. He (lbn Sa`d) said: When the news of Farwah’s embracing
Islam reached the Roman Emperor, he called him and said to him:
Abandon your creed and we will make you ruler. He said: I shall not part
with the creed of Muhammad; and you know that Jesus gave the good
news of his advent, but you fear because of your empire. Thereupon he
imprisoned him and subsequently brought him out and killed him, and
then crucified (his corpse).
