AbdurRahman ibn Ka'b ibn Malik reported on the authority of a man from among the companions of the Prophet (saws): The infidels of the Quraysh wrote (a letter) to Ibn Ubayy and to those who worshipped idols from al-Aws and al-Khazraj, while the Messenger of Allah (saws) was at that time at Medina before the battle of Badr.

(They wrote): You gave protection to our companion. We swear by Allah, you should fight him or expel him, or we shall come to you in full force, until we kill your fighters and appropriate your women.

When this (news) reached Abdullah ibn Ubayy and those who were worshippers of idols, with him they gathered together to fight the Messenger of Allah (saws).

When this news reached the Messenger of Allah (saws), he visited them and said: The threat of the Quraysh to you has reached its end. They cannot contrive a plot against you, greater than what you yourselves intended to harm you. Are you willing to fight your sons and brethren? When they heard this from the Prophet (saws), they scattered. This reached the infidels of the Quraysh.

The infidels of the Quraysh again wrote (a letter) to the Jews after the battle of Badr: You are men of weapons and fortresses. You should fight our companion or we shall deal with you in a certain way. And nothing will come between us and the anklets of your women. When their letter reached the Prophet (saws), they gathered Banu an-Nadir to violate the treaty.

They sent a message to the Prophet (saws): Come out to us with thirty men from your companions, and thirty rabbis will come out from us till we meet at a central place where they will hear you. If they testify to you and believe in you, we shall believe in you. The narrator then narrated the whole story.

When the next day came, the Messenger of Allah (saws) went out in the morning with an army, and surrounded them.

He told them: I swear by Allah, you will have no peace from me until you conclude a treaty with me. But they refused to conclude a treaty with him. He therefore fought them the same day.

Next he attacked Banu Quraysh with an army in the morning, and left Banu an-Nadir. He asked them to sign a treaty and they signed it.

He turned away from them and attacked Banu an-Nadir with an army. He fought with them until they agreed to expulsion. Banu an-Nadir were ...

Malik related to me that he heard that Umm Salama, the wife of the Prophet, may Allah bless him and grant him peace, made a settlement with her mukatab for an agreed amount of gold and silver.

Malik said, "The generally agreed on way of doing things among us in the case of a mukatab who is shared by two partners, is that one of them cannot make a settlement with him for an agreed price according to his portion without the consent of his partner. That is because the slave and his property are owned by both of them, and so one of them is not permitted to take any of the property except with the consent of his partner. If one of them settled with the mukatab and his partner did not, and he took the agreed price, and then the mukatab died while he had property or was unable to pay, the one who settled would not have anything of the mukatab's property and he could not return that for which he made settlement so that his right to the slave's person would return to him. However, when someone settles with a mukatab with the permission of his partner and then the mukatab is unable to pay, it is preferable that the one who broke with him return what he has taken from the mukatab for the severance and he can have back his portion of the mukatab. He can do that. If the mukatab dies and leaves property, the partner who has kept hold of the kitaba is paid in full the amount of the kitaba which remains to him against the mukatab from the mukatab's property. Then what remains of property of the mukatab is between the partner who broke with him and his partner, according to their shares in the mukatab. If one of the partners breaks off with him and the other keeps the kitaba, and the mukatab is unable to pay, it is said to the partner who settled with him, 'If you wish to give your partner half of what you took so the slave is divided between you, then do so. If you refuse, then all of the slave belongs to the one who held on to possession of the slave.' "

Malik spoke about a mukatab who was shared between two men and one of them made a settlement with him with the permission of his partner. Then the one who retained possession of the slave demanded the like of that for which his partner had settled or more than that and the mukatab could not pay it. He said, "The mukatab is shared between them because the man has only demanded what is owed to him. If he demands less than what the one who settled with him took and the mukatab can not manage that, and ...
