(3) CHAPTER. The Prophet estabilished the bone of brotherhood (fraternity) between the Ansar and the Muhajirun (i.e., emigrants).
Narrated Sa`d's father: When the emigrants reached Medina. Allah's Apostle established the bond of fraternity between `Abdur-Rahman and Sa`d bin Ar-Rabi. Sa`d said to `Abdur-Rahman, I am the richest of all the Ansar, so I want to divide my property (between us), and I have two wives, so see which of the two you like 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 your family and property for you; where is your market? So they showed him the Qainuqa' market. (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 scent. The Prophet asked, What is this (scent)? He replied, I got married. The Prophet 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 is correct.)
Narrated Anas: When `Abdur-Rahman bin `Auf came to us, Allah's Apostle made a bond of fraternity between him and Sa`d bin Ar-Rabi` who was a rich man, Sa`d said, The Ansar know that I am the richest of all of them, so I will divide my property into two parts between me and you, and I have two wives; see which of the two you like so that I may divorce her and you can marry her after she becomes lawful to you by her passing the prescribed period (i.e. 'Idda) of divorce. `Abdur Rahman said, May Allah bless you your family (i.e. wives) for you. (But `Abdur-Rahman went to the market) and did not return on that day except with some gain of dried yogurt and butter. He went on trading just a few days till he came to Allah's Apostle bearing the traces of yellow scent over his clothes. Allah's Apostle asked him, What is this scent? He replied, I have married a woman from the Ansar. Allah's Apostle asked, How much Mahr have you given? He said, A date-stone weight of gold or a golden date-stone. The Prophet said, Arrange a marriage banquet even with a sheep.
Narrated Abu Huraira: The Ansar said (to the Prophet ), Please divide the date-palm trees between us and them (i.e. emigrants). The Prophet said, No. The Ansar said, Let them (i.e. the emigrants) do the labor for us in the gardens and share the date-fruits with us. The emigrants said, We accepted this.
