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