Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I heard the Prophet (peace and blessings be upon him) saying: "Who will take this letter of mine to the tyrants of Rome?" The Prophet (peace and blessings be upon him) put this before the people three times. After that he said: "Whoever takes it will have Paradise." A man from the Ansar whose name was Ubaydullah bin Abd al-Khaliq said: "I will take it, so that in return I get Paradise, even if I perish before that." The Prophet (peace and blessings be upon him) said: "Very well, you will have Paradise whether you deliver it (to the person concerned) or are killed; and if you perish, then too Allah Almighty will make Paradise binding for you." He took the letter of the Prophet (peace and blessings be upon him) until, when he reached the tyrants and told them, "I am the envoy of the Messenger of Allah to you," they gave him permission and he entered. The tyrants of Rome realised that he had brought the truth from a Prophet who had been sent. Then he presented the letter of the Prophet (peace and blessings be upon him) before him, and that man gathered the people of Rome to himself and then put it before them, and they disliked what the envoy had brought. One man among them believed in it, and as soon as he believed he was killed. Then that Companion returned to the Prophet (peace and blessings be upon him) and told him about the situation there and about that man. On that occasion the Prophet (peace and blessings be upon him) said: "On the Day of Resurrection Allah Almighty will raise him as a nation by himself." (The narrator says:) He said this about that slain man.
Tabarani recorded it. Its chain contains Yahya bin Abdullah al-Babulti, who is da'if (weak).
