Narrated `Abdullah bin `Abbas:
Allah's Apostle wrote to Caesar and invited him to Islam and sent him his letter with Dihya Al-Kalbi whom Allah's Apostle ordered to hand it over to the Governor of Busra who would forward it to Caesar. Caesar as a sign of gratitude to Allah, had walked from Hims to Ilya (i.e. Jerusalem) when Allah had granted Him victory over the Persian forces. So, when the letter of Allah's Apostle reached Caesar, he said after reading it, 'Seek for me any one of his people! (Arabs of Quraish tribe) if present here, in order to ask him about Allah's Apostle. At that time Abu Sufyan bin Harb was in Sham with some men from Quraish who had come (to Sham) as merchants during the truce that had been concluded between Allah's Apostle; and the infidels of Quraish. Abu Sufyan said, Caesar's messenger found us somewhere in Sham so he took me and my companions to Ilya and we were admitted into Ceasar's court to find him sitting in his royal court wearing a crown and surrounded by the senior dignitaries of the Byzantine.

Had it not been shameful that my companions label me a liar, I would not have spoken the truth about him when he asked me. But I considered it shameful to be called a liar by my companions. So I told the truth. He then said to his translator, 'Ask him what kind of family does he belong to.' I replied, 'He belongs to a noble family amongst us.' He said, 'Have anybody else amongst you ever claimed the same before him? 'I replied, 'No.' He said, 'Had you ever blamed him for telling lies before he claimed what he claimed? ' I replied, 'No.' He said, 'Was anybody amongst his ancestors a king?' I replied, 'No.' He said, "Do the noble or the poor follow him?' I replied, 'It is the poor who follow him.'
