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. He said to his translator. 'Ask them who amongst them is a close relation to the man who claims to be a prophet." Abu Sufyan added, "I replied, 'I am the nearest relative to him.' He asked, 'What degree of relationship do you have with him?' I replied, 'He is my cousin,' and there was none of Bani Abu Manaf in the caravan except myself. Caesar said, 'Let him come nearer.' He then ordered that my companions stand behind me near my shoulder and said to his translator, 'Tell his companions that I am going to ask this man about the man who claims to be a prophet. If he tells a lie, they should contradict him immediately." Abu Sufyan added, "By Allah! 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.' He said, 'Are they increasing or decreasing (day by day)?' I replied,' They are increasing.' He said, 'Does anybody amongst those who embrace his (the Prophet's) Religion become displeased and then discard his Religion?'. I replied, 'No. ' He said, 'Does he break his promises? I replied, 'No, but we are now at truce with him and we are afraid that he may betray us." Abu Sufyan added, "Other than the last sentence, I could not say anything against him. Caesar then asked, 'Have you ever had a war with him?' I replied, 'Yes.' He said, 'What was the outcome of your battles with him?' I replied, 'The result was unstable; sometimes he was victorious and sometimes we.' He said, 'What does he order you to do?' I said, 'He tells us to worship Allah alone, and not to worship others along with Him, and to leave all that our fore-fathers used to worship. He orders us to pray, give in charity, be chaste, keep promises and return what is entrusted to us.' When I had said that, Caesar said to his translator, 'Say to him: I ask you about his lineage and your reply was that he belonged to a noble family. In fact, all the apostles came from the noblest lineage of their nations. Then I questioned you whether anybody else amongst you had claimed such a thing, and your reply was in the negative. If the answer had been in the affirmative, I would have thought that this man was following a claim that had been said before him. When I asked you whether he was ever blamed for telling lies, your reply was in the negative, so I took it for granted that a person who did not tell a lie about (others) the people could never tell a lie about Allah. Then I asked you whether any of his ancestors was a king. Your reply was in the negative, and if it had been in the affirmative, I would have thought that this man wanted to take back his ancestral kingdom. When I asked you whether the rich or the poor people followed him, you replied that it was the poor who followed him. In fact, such are the followers of the apostles. Then I asked you whether his followers were increasing or decreasing. You replied that they were increasing. In fact, this is the result of true faith till it is complete (in all respects). I asked you whether there was anybody who, after embracing his religion, became displeased and discarded his religion; your reply was in the negative. In fact, this is the sign of true faith, for when its cheerfulness enters and mixes in the hearts completely, nobody will be displeased with it. I asked you whether he had ever broken his promise. You replied in the negative. And such are the apostles; they never break their promises. When I asked you whether you fought with him and he fought with you, you replied that he did, and that sometimes he was victorious and sometimes you. Indeed, such are the apostles; they are put to trials and the final victory is always theirs. Then I asked you what he ordered you. You replied that he ordered you to worship Allah alone and not to worship others along with Him, to leave all that your fore-fathers used to worship, to offer prayers, to speak the truth, to be chaste, to keep promises, and to return what is entrusted to you. These are really the qualities of a prophet who, I knew (from the previous Scriptures) would appear, but I did not know that he would be from amongst you. If what you say should be true, he will very soon occupy the earth under my feet, and if I knew that I would reach him definitely, I would go immediately to meet Him; and were I with him, then I would certainly wash his feet.' " Abu Sufyan added, "Caesar then asked for the letter of Allah's Apostle and it was read. Its contents were: "In the name of Allah, the most Beneficent, the most Merciful (This letter is) from Muhammad, the slave of Allah, and His Apostle, to Heraculius, the Ruler of the Byzantine. Peace be upon the followers of guidance. Now then, I invite you to Islam (i.e. surrender to Allah), embrace Islam and you will be safe; embrace Islam and Allah will bestow on you a double reward. But if you reject this invitation of Islam, you shall be responsible for misguiding the tillers (i.e. your nation). O people of the Scriptures! Come to a word common to you and us and you, that we worship. None but Allah, and that we associate nothing in worship with Him; and that none of us shall take others as Lords besides Allah. Then if they turn away, say: Bear witness that we are (they who have surrendered (unto Him)..(3.64) Abu Sufyan added, "When Heraclius had finished his speech, there was a great hue and cry caused by the Byzantine Royalties surrounding him, and there was so much noise that I did not understand what they said. So, we were turned out of the court. When I went out with my companions and we were alone, I said to them, 'Verily, Ibn Abi Kabsha's (i.e. the Prophet's) affair has gained power. This is the King of Bani Al-Asfar fearing him." Abu Sufyan added, "By Allah, I remained low and was sure that his religion would be victorious till Allah converted me to Islam, though I disliked it."

While I was at home, the sun rose high and it got hot. Suddenly the messenger of `Umar bin Al- Khattab came to me and said, "The chief of the believers has sent for you." So, I went along with him till I entered the place where `Umar was sitting on a bedstead made of date-palm leaves and covered with no mattress, and he was leaning over a leather pillow. I greeted him and sat down. He said, "O Mali! Some persons of your people who have families came to me and I have ordered that a gift should be given to them, so take it and distribute it among them." I said, "O chief of the believers! I wish that you order someone else to do it." He said, "O man! Take it." While I was sitting there with him, his doorman Yarfa' came saying, "`Uthman, `Abdur-Rahman bin `Auf, Az-Zubair and Sa`d bin Abi Waqqas are asking your permission (to see you); may I admit them?" `Umar said, "Yes", So they were admitted and they came in, greeted him, and sat down. After a while Yarfa' came again and said, "May I admit `Ali and `Abbas?" `Umar said, "yes." So, they were admitted and they came in and greeted (him) and sat down. Then `Abbas said, "O chief of the believers! Judge between me and this (i.e. `Ali)." They had a dispute regarding the property of Bani An-Nadir which Allah had given to His Apostle as Fai. The group (i.e. `Uthman and his companions) said, "O chief of the believers! Judge between them and relieve both of them front each other." `Umar said, "Be patient! I beseech you by Allah by Whose Permission the Heaven and the Earth exist, do you know that Allah's Apostle said, 'Our (i.e. prophets') property will not be inherited, and whatever we leave, is Sadaqa (to be used for charity),' and Allah's Apostle meant himself (by saying "we'')?" The group said, "He said so." `Umar then turned to `Ali and `Abbas and said, "I beseech you by Allah, do you know that Allah's Apostle said so?" They replied, " He said so." `Umar then said, "So, I will talk to you about this matter. Allah bestowed on His Apostle with a special favor of something of this Fai (booty) which he gave to nobody else." `Umar then recited the Holy Verses: "What Allah bestowed as (Fai) Booty on his Apostle (Muhammad) from them --- for this you made no expedition with either cavalry or camelry: But Allah gives power to His Apostles over whomever He will 'And Allah is able to do all things." 9:6) `Umar added "So this property was especially given to Allah's Apostle, but, by Allah, neither did he take possession of it and leave your, nor did he favor himself with it to your exclusion, but he gave it to all of you and distributed it amongst you till this property remained out of it. Allah's Apostle used to spend the yearly expenses of his family out of this property and used to keep the rest of its revenue to be spent on Allah 's Cause. Allah 's Apostle kept on doing this during all his lifetime. I ask you by Allah do you know this?" They replies in the affirmative. `Umar then said to `Ali and `Abbas. "I ask you by Allah, do you know this?" `Umar added, "When Allah had taken His Prophet unto Him, 'Abu Bakr said, 'I am the successor of Allah's Apostle so, Abu Bakr took over that property and managed it in the same way as Allah's Apostle used to do, and Allah knows that he was true, pious and rightlyguided, and he was a follower of what was right. Then Allah took Abu Bakr unto Him and I became Abu Bakr's successor, and I kept that property in my possession for the first two years of my Caliphate, managing it in the same way as Allah's Apostle used to do and as Abu Bakr used to do, and Allah knows that I have been true, pious, rightly guided, and a follower of what is right. Now you both (i.e. 'Ah and `Abbas) came to talk to me, bearing the same claim and presenting the same case; you, `Abbas, came to me asking for your share from your nephew's property, and this man, i.e. `Ali, came to me asking for his wife's share from her father's property. I told you both that Allah's Apostle said, 'Our (prophets') properties are not to be inherited, but what we leave is Sadaqa (to be used for charity).' When I thought it right that I should hand over this property to you, I said to you, 'I am ready to hand over this property to you if you wish, on the condition that you would take Allah's Pledge and Convention that you would manage it in the same way as Allah's Apostle used to, and as Abu Bakr used to do, and as I have done since I was in charge of it.' So, both of you said (to me), 'Hand it over to us,' and on that condition I handed it over to you. So, I ask you by Allah, did I hand it over to them on this condition?" The group aid, "Yes." Then `Umar faced `Ali and `Abbas saying, "I ask you by Allah, did I hand it over to you on this condition?" They said, "Yes. " He said, " Do you want now to give a different decision? By Allah, by Whose Leave both the Heaven and the Earth exist, I will never give any decision other than that (I have already given). And if you are unable to manage it, then return it to me, and I will do the job on your behalf."
