It was narrated from Anas that 'Abdur-Rahman bin 'Awf came with a trace of saffron on him, and the Messenger of Allah said: "What's this for?" He said: "I have married a woman." He said: "What dowry did you give?" He said: "The weight of a Nawah (five Dirhams) of gold." He said: "Give a Walimah (wedding feast) even if it is with one sheep." Translation Not Available
