Narrated Abu Rafi: The Quraysh sent me to the Messenger of Allah ﷺ, and when I saw the Messenger of Allah ﷺ, Islam was cast into my heart, so I said: Messenger of Allah, I swear by Allah, I shall never return to them. The Messenger of Allah ﷺ replied: I do not break a covenant or imprison messengers, but return, and if you feel the same as you do just now, come back. So I went away, and then came to the Prophet ﷺ and accepted Islam. The narrator Bukair said: He informed me that Abu Rafi was a Copt. Abu Dawud said: This was valid in those days, but today it is not valid.

Narrated Amr ibn Abasah: Sulaym ibn Amir, a man of Himyar, said: There was a covenant between Muawiyah and the Byzantines, and he was going towards their country, and when the covenant came to an end, he attacked them. A man came on a horse, or a packhorse saying, Allah is Most Great, Allah is Most Great; let there be faithfulness and not treachery. And when they looked they found that he was Amr ibn Abasah. Muawiyah sent for him and questioned him (about that). He said: I heard the Messenger of Allah ﷺ say: When one has covenant with people he must not strengthen or loosen it till its term comes to an end or he brings it to an end in agreement with them (to make both the parties equal). So Muawiyah returned.

Narrated Abu Bakrah: The Prophet ﷺ said: If anyone kills a man whom he grants protection prematurely, Allah will forbid him to enter Paradise.

Narrated Nuaym ibn Masud: I heard the Messenger of Allah ﷺ say when he read the letter of Musaylimah: What do you believe yourselves? They said: We believe as he believes. He said: I swear by Allah that were it not that messengers are not killed, I would cut off your heads.

Narrated Abdullah ibn Masud: Harithah ibn Mudarrib said that he came to Abdullah ibn Masud and said (to him): There is no enmity between me and any of the Arabs. I passed a mosque of Banu Hanifah. They (the people) believed in Musaylimah. Abdullah (ibn Masud) sent for them. They were brought, and he asked them to repent, except Ibn an-Nawwahah. He said to him: I heard the Messenger of Allah ﷺ say: Were it not that you were not a messenger, I would behead you. But today you are not a messenger. He then ordered Qarazah ibn Kab (to kill him). He beheaded him in the market. Anyone who wants to see Ibn an-Nawwahah slain in the market (he may see him).

Ibn Abbas said “Umm Hani daughter of Abu Talib told me that in the year of the conquest she gave protection to a man from the polytheists. She came to the Prophet ﷺ and mentioned it to him. He said “We have given security to those to whom you have given it. ”

Narrated Aishah, Ummul Muminin: A woman would give security from the believers and it would be allowed.

Al Miswar bin Makhramah said: The Messenger of Allah ﷺ came out in the year of al-Hudaibbiyyah with over ten hundreds of Companions and when he came to Dhu al Hulaifah. He garlanded and marked the sacrificial animals, and entered the sacred state of Umrah. He then went on with the tradition. The Prophet moved on and when he came to the mountain, pass by which one descends (to Makkah) to them, his riding-beast knelt down, and the people said twice: Go on, go on, al-Qaswa has become jaded. The Prophet ﷺ said: She has not become jaded and that is not a characteristic of hers, but He Who restrained the elephant has restrained her. He then said: By Him in Whose hand my soul is, they will not ask any me good thing by which they honor which God has made sacred without my giving them it. He then urged her and she leaped up and he turned aside from them, and stopped at the farthest side of al-Hudaibiyyah at a pool with little water. Meanwhile Budail bin Warqa al-Khuza’I came, and Urwah bin Masud joined him. He began to speak to the Prophet ﷺ. Whenever he spoke to the Prophet ﷺ, he caught his beard. Al Mughriah bin Shubah was standing beside the Prophet ﷺ. He had a sword with him, wearing a helmet. He (Al Mughriah) struck his (Urwah’s) hand with the lower end of his sheath, and said: Keep away your hand from his beard. Urwah then raised his hand and asked: Who is this? They replied: Al-Mughirah bin Shubah. He said: O treacherous one! Did I not use my offices in your treachery? In pre-Islamic days Al-Mughirah bin Shubah accompanied some people and murdered them, and took their property. He then came (to the Prophet) and embraced Islam. The Prophet ﷺ said: As for Islam we accepted it, but as to the property, as it has been taken by treachery, we have no need of it. He went on with the tradition the Prophet ﷺ said: Write down: This is what Muhammad, the Messenger of Allah, has decided. He then narrated the tradition. Suhail then said: And that a man will not come to you from us, even if he follows your religion, without you sending him back to us. When he finished drawing up the document, the Prophet ﷺ said to his Companions: Get up and sacrifice and then shave. Thereafter some believing women who were immigrants came. (Allah sent down: O yea who believe, when believing women come to you as emigrants). Allah most high forbade them to send them back, but ordered them to restore the dower. He then returned to Madina. Abu Basir a man from the Quraish (who was a Muslim), came to him. And they sent (two men) to look for him; so he handed him over to the two men. They took him away, and when they reached Dhu Al Hulaifah and alighted to eat some dates which they had, Abu Basir said to one of the men: I swear by Allah so-and-so, that I think this sword of yours is a fine one; the other drew the sword and said: Yes I have tried it. Abu Basir said: Let me look at it. He let him have it and he struck him till he died, whereupon the other fled and came to Madina, and running entered the mosque. The Prophet ﷺ said: This man has seen something frightful. He said: I swear by Allah that my Companion has been killed, and im as good as dead. Abu Basir then arrived and said: Allah has fulfilled your covenant. You returned me to them, but Allah saved me from them. The Prophet ﷺ said: Woe to his mother, stirrer up of war! Would that he had someone (i. e. some kinsfolk). When he heard that he knew that he would send him back to them, so he went out and came to the seashore. Abu Jandal escaped and joined Abu Basir till a band of them collected.

Al Miswar bin Makhramah and Marwan bin Al Hakam said “They agreed to abandon war for ten years during which the people which have security on the basis that there should be sincerity between them and that there should be not theft or treachery.
