Sahih al-Bukhari 5072

Muḥammad ibn Kathīr narrated to us, from Sufyān, from Ḥumayd al-Ṭawīl, who said: I heard Anas ibn Mālik say: ʿAbd al-Raḥmān ibn ʿAwf arrived, and the Prophet established a bond of brotherhood between him and Saʿd ibn al-Rabīʿ al-Anṣārī. The Anṣārī had two wives and offered to share his family and wealth equally with him. ʿAbd al-Raḥmān said, ‘May Allah bless you in your family and wealth. Show me the marketplace.’ He went to the market and earned some dried curds and some ghee. A few days later, the Prophet saw him with a yellow stain on him and asked, ‘What is this, ʿAbd al-Raḥmān?’ He replied, ‘I married an Anṣārī woman.’ He asked, ‘What bridal gift did you give?’ He replied, ‘Gold weighing a date stone.’ He said, ‘Hold a wedding feast, even if with one sheep.’
