The following was recorded in Sahih Al-Bukhari (5/31/3780) under the chapter heading “The Prophet (peace be upon him) forming a brotherhood between the Muhajirin and the Ansar” as related by Ibrahim bin Sa’d from his father from his grandfather who said:

Lokacin da Muhajirai (baƙi daga Makka) suka isa Madina, Manzon Allah ﷺ ya kafa zumuncin ɗan'uwantaka tsakanin Abdur Rahman bin ‘Auf da Sa’d bin Ar-Rabi’. Sa’d ya ce wa Abdur Rahman: “Ni ne mafi wadata daga cikin dukan Ansar, don haka ina so in raba dukiyata gida biyu tsakaninmu, kuma ina da mata biyu, sai ka duba wacce daga cikinsu ka fi so, ka faɗa mini, domin in sake ta, sa'an nan idan ta gama lokacin idda, sai ka aure ta.” Abdur Rahman ya ce: “Allah ya albarkaci iyalinka da dukiyarka; ina kasuwarku?” Sai suka nuna masa kasuwar Banu Qainuqa’. (Ya je can) ya dawo da riba a cikin nau'in yogurt busasshe da man shanu. Ya ci gaba da zuwa kasuwar har wata rana ya zo yana ɗauke da alamun rawaya a jikinsa. Manzon Allah ﷺ ya tambaya: “Menene wannan (ƙamshi)?” Ya amsa: “Na yi aure.” Manzon Allah ﷺ ya tambaya: “Nawa ne sadakin da ka ba ta?” Ya amsa: “Na ba ta kwayar dabino ta zinariya, ko wani yanki na zinariya mai nauyin kwayar dabino.” (Mai ruwaito, Ibrahim, yana shakka game da wacce ce daidai.)
“When the Muhajirun (emigrants) arrived in Al-Madinah, Allah's Messenger (peace be upon him) established the bond of brotherhood between Abdur Rahman bin ‘Awf and Sa’d bin Ar-Rabee’. Sa’d said to Abdur Rahman: “I am the wealthiest of all the Ansar, so I want to divide my wealth in half between us, and I have two wives, so see which of the two you like the most and tell me, so that I may divorce her, and when she finishes her prescribed period (i.e. 'Idda) of divorce, then marry her." Abdur-Rahman said, "May Allah bless you in your family and property; where is your marketplace?” So, they guided him to the marketplace of Bani Qainuqaa’. (He went there and) returned with a profit in the form of dried yogurt and butter. He continued going (to the market) till one day he came, bearing the traces of yellow on him. The Prophet (peace be upon him) asked: “What is this (scent)?” He replied: “I got married”. The Prophet (peace be upon him) asked: “How much Mahr did you give her?” He replied: “I gave her a datestone of gold or a gold piece equal to the weight of a date-stone”. (The narrator, Ibrahim, is in doubt as to which was correct.)
An Ruwaito shi a cikin Sahih Al-Bukhari (5/31/3781) daga Anas, Allah ya yarda da shi, wanda ya ce:
It was also related in Sahih Al-Bukhari (5/31/3781) from Anas, may Allah be pleased with him, who said:

Lokacin da Abdur Rahman bin ‘Awf ya zo wurinmu (watau a Madinah), Manzon Allah ﷺ ya kafa zumunci tsakaninsa da Sa’d bin Ar-Rabee’, kuma yana da dukiya mai yawa. Sa’d ya ce: “Ansar sun sani cewa ni ina cikin waɗanda suka fi dukiya a cikinsu, saboda haka zan raba dukiyata tsakaninmu rabi-rabi. Kuma ina da mata biyu, sai ka duba ka ga wacce daga cikinsu ta fi faranta maka rai, sai in sake ta, idan ta kammala idadin iddarta, za ka iya aure ta.” Abdur Rahman ya ce: “Allah ya albarkaci iyalinka.” Sannan bai dawo a wannan rana ba sai da wasu cuku da mai da ya samu a matsayin riba. Ba da daɗewa ba, sai ya zo wurin Manzon Allah ﷺ, sai ga alamar turaren rawaya a jikinsa. Manzon Allah ﷺ ya ce masa: “Me ke nan?” Ya amsa: “Na auri wata mace daga cikin Ansar.” Ya tambaya: “Wane sadaki ka ba ta?” Ya amsa: “Nauyin kwayar dabino na zinare,” ko kuma ya ce: “Kwayar dabino ta zinare.” Sai ya ce: “Ka yi walima, koda da tunkiya ɗaya ne.” ﷺ
“When Abdur Rahman bin ‘Awf came to us (i.e. in Al-Madinah), the Messenger of Allah (peace be upon him) established a bond of brotherhood between him and Sa’d bin Ar-Rabee’ and he had a lot of wealth. Sa’d said: “The Ansar know that I am from those who have the most wealth among them, so I will divide my wealth between us in half. And I have two wives, so look to see which of the two pleases you the most and I will divorce her, and when she completes her waiting period you may marry her”. Abdur Rahman said: “May Allah bless you in your family”. Then he did not return that day except with some cottage cheese and cooking fat which he had earned as a profit. It wasn’t long thereafter, until he came to the Messenger of Allah (peace be upon him) and he had traces of yellow scent on him. The Messenger of Allah (peace be upon him) then said to him: “What is this?” He replied: “I married a woman from the Ansar”. He asked: “What dowry did you give her?” He answered: “The weight of date- stone of gold" Or he said: “A date-stone of gold” So, he (peace be upon him) said: “Have a banquet (Walimah), even if with only one sheep”.
An ruwaito a cikin Sahih Al-Bukhari (5/32/3782) cewa Abu Hurairah, Allah ya yarda da shi, ya ce:
It was related in Sahih Al-Bukhari (5/32/3782) that Abu Hurairah, may Allah be pleased with him, said:
Ansarawa sun ce wa Annabi ﷺ:
The Ansar said to the Prophet (peace be upon him):

"Ku raba itatuwan dabino tsakaninmu da su (watau Muhajirun)." Sai ya amsa: "A'a." Ya ce: "Ya isar mana mu taimaka (watau a aikin), su kuma su raba mana dabinon." Suka ce: "Mun ji, kuma muna biyayya."
“Divide the date palm trees between us and them (i.e. the Muhajirun)" He replied: “No”. He said: “It is sufficient for us to assist (i.e. in the work) and they share the dates with us” They said: “We listen and obey”. .

Ibn Abdul Barr ya ce kafa 'yan'uwantaka ta faru sau biyu: sau ɗaya tsakanin Muhajirai musamman, wanda ya faru a Makka, da kuma sau ɗaya tsakanin Muhajirai da Ansar, kuma shi ne wanda ake nufi a nan.

We find the details and features of this “Mu’akhaah” (bonding of brotherhood) in Ibn Hajar’s “Fat’h ul-Bariy (7/270): “We have presented in respect to the qualities of the Ansar the chapter heading of the forming of brotherhood by the Prophet (peace be upon him) between the Muhajirin and the Ansar. Ibn Abdul Barr said that the formation of brotherhood occurred on two occasions; an occasion between the Muhajirin specifically which was in Makkah and an occasion between the Muhajirin and the Ansar, and it is the latter which is intended here. Ibn Sa’d mentioned, with the chains of transmission of Al-Waqidiy from a group of the Taabi’in who said: “When the Prophet (peace be upon him) arrived in Al-Madinah he formed a bond of brotherhood between the Muhajirin and the Ansar upon the basis of Al-Muwasaah (supporting one another) and they use to inherit from one another. They numbered ninety; some from the Muhajirin and some from the Ansar. It was also said that they numbered one hundred. When the Aayah related to “those tied by the womb” (8:75) was revealed the inheritance between in accordance to that brotherhood (Mu’akhaah) between them was negated. In the chapter of the “Faraa’id” (rules of inheritance), the Hadith of Ibn ‘Abbas will be mentioned: “When they arrived in Al-Madinah the Muhajiriy would inherit from the Ansariy, instead of those joined by the womb, through the bond of brotherhood that the Messenger of Allah (peace be upon him) instituted, then the following was revealed …” .
