Sayyidina Anas (RA) narrated: When Abdul Rahman ibn Awf (RA) came to Madinah, Allah’s Messenger (SAW) established fraternal ties between him and Sa’d ibn Rabi.’ He said to him, “Come, I will apportion to you my wealth, half of it. And, I have two wives, so I will divorce one of them and when she completes her waiting period, you may marry her. But, he said, ‘May Allah bless you in your family and your wealth. Guide me to the market.” So, he led him to the market. That very day, he did not return but he had with him some cheese and clarified butter which was his profit. Later (after some days), Allah’s Messenger saw him and he had a yellow stain on him and asked him about it. He said, “I have married an Ansar woman.” The Prophet (SAW) asked, “How much dower have you given her?” He said, ‘Nawat of gold.” He said, “Give a wedding feast, even a sheep.”
