It was narrated from Humaid At-TawIi that he heard Anas say: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم established the bond of brotherhood between (some of) the Quraish and (some of) the Ansar, and he established the bond of brotherhood between Saad bin Ar Rabi’ and ‘Abdur-Rahman bin ‘Awf. Saad said to him: ‘I have wealth, which I will share equally between you and me. And I have two wives, so look and see which one you like better, and I will divorce her, and when her ‘Iddah is over you can marry her.’ He said:
‘May Allah bless your family and your wealth for you. Show me — i.e., where the market is.’ And he did not come back until he brought some ghee, and cottage cheese that he had left over. He said: ‘The Messenger of Allah صلی اللہ علیہ وآلہ وسلم saw traces of yellow perfume on me and he said: ‘What is this for?’ I said: ‘I have married a woman from among the Ansar.’ He said: ‘Give a WalImah (wedding feast) even if it is with one sheep.” (Sahih)
