Sayyiduna Anas bin Malik (may Allah be pleased with him) said: Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) married a woman of the Ansar for gold equal to the weight of a date stone. When the Prophet (peace and blessings be upon him) saw the joy of the wedding on him, he asked, and Abd al-Rahman (may Allah be pleased with him) said: "I have married a woman for gold equal to the weight of a date stone."
