It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) arrived in Madinah Munawwarah, the Noble Prophet (peace and blessings be upon him) established brotherhood and companionship between him and Sayyiduna Sa’d bin Rabi’ (may Allah be pleased with him). Sayyiduna Sa’d (may Allah be pleased with him) said: I will divide all my wealth in half, and I have two wives; I will divorce one of them, and after her waiting period is complete, you may marry her. Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) said: May Allah bless your family and your wealth, but I do not need these things; just show me the way to the market and bazaar. The people showed him the way to the market, and he went there. When he returned, he had some cheese and some ghee with him, which he had earned as profit. After that, on one occasion, the Messenger of Allah (peace and blessings be upon him) saw him and there was yellow color on his clothes. The Prophet (peace and blessings be upon him) asked: What is this? He replied: I have married an Ansari woman. The Prophet (peace and blessings be upon him) asked: What did you give her as dowry? He replied: Gold equal to the weight of a date stone. The Messenger of Allah (peace and blessings be upon him) said: Hold a wedding feast, even if it is with only one goat.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) established brotherhood and fraternity between the Quraysh and the Ansar in my house, which is in Madinah Munawwarah.

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that someone said to him: "Do you know that the Messenger of Allah (peace and blessings be upon him) said that there is no brotherhood (Mu’akhāt) in Islam?" Upon hearing this, Sayyiduna Anas (may Allah be pleased with him) became angry and said, "Why not, why not! Rather, the Messenger of Allah (peace and blessings be upon him) himself established brotherhood between the Quraysh and the Ansar in my house."

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that someone said to him: "Do you know that the Messenger of Allah (peace and blessings be upon him) said that there is no brotherhood (Mu’akhāt) in Islam?"

Rather, the Messenger of Allah (peace and blessings be upon him) himself established brotherhood between the Quraysh and the Ansar in my house."

(Second chain) It is narrated from Asim Ahwal that the Messenger of Allah, peace and blessings be upon him, established brotherhood between the Muhajirin and the Ansar in the house of Sayyiduna Anas bin Malik, may Allah be pleased with him.

It is narrated from Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: There is no mutual covenant in Islam, but any covenant or pact that was made in the pre-Islamic era of ignorance, Islam strengthens and reinforces it.

It is narrated from Qais bin Asim that he asked the Holy Prophet, peace and blessings be upon him, about covenants and agreements. The Prophet, peace and blessings be upon him, said: Fulfill the covenants and agreements that you made during the time of ignorance, but in Islam, there are no such new covenants and agreements.

It is narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When I was still a boy, I participated with my uncles in the pact of Mutayyibeen. Even now, if I were to be given the most precious red camels, I would not like to break that pact. Imam Zuhri says: The Messenger of Allah (peace and blessings be upon him) said: Islam has further strengthened any pact that it found people had made, and now, in Islam, there is no room for such covenants and agreements. The Messenger of Allah (peace and blessings be upon him) himself established brotherhood between the Quraysh and the Ansar.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The agreements and covenants made during the Age of Ignorance have been further strengthened and reinforced by Islam.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Muhajirun said: Among the Ansar people we have come to, we have not found anyone more generous in spending or more compassionate despite having little than them. They fulfilled all our needs and included us in all their joys. We fear that they will take all the reward. But the Messenger of Allah (peace and blessings be upon him) said: No, it is not so, as long as you praise them for their good conduct and pray to Allah for them, (Allah will also grant you its reward).
