It was narrated from Humaid At-Tawil that he heard Anas say: "The Messenger of Allah established the bond of brotherhood between (some of) the Quraish and (some of) the Ansar, and he established the bond of brotherhood between Sa'd bin Ar-Rabi' and 'Abdur-Rahman bin 'Awf. Sa'd 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 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.'"
