What was the Prophet Muhammad (saw)'s reaction when he saw a yellow mark (of perfume) on the clothes of `Abdur-Rahman bin `Auf?
 Narrated Anas:                     The Prophet seeing a yellow mark (of perfume) on the clothes of `Abdur-Rahman bin `Auf, said, "What about you?" `Abdur-Rahman replied, "I have married a woman with a Mahr of gold equal to a date-stone." The Prophet said, "May Allah bestow His Blessing on you (in your marriage). Give a wedding banquet, (Walima) even with one sheep."
