It was narrated from Anas bin Malik that 'Abdur-Rahman bin 'Awf came to the Prophet with traces of yellow perfume on him. The Messenger of Allah asked him (about that) and he told him that he had married a woman from among the Ansar. The Messenger of Allah said: "How much did you give her?" He said: "A Nawah (five Dirhams) of gold." The Messenger of Allah said: "Give a Walimah (wedding feast) even if it is with one sheep"
