Volume 7, Book 62, Number 78:
Narrated Anas:
Abdur Rahman bin ‘Auf married a woman and gave her gold equal to the weight of a date stone
(as Mahr). When the Prophet noticed the signs of cheerfulness of the marriage (on his face) and
asked him about it, he said, “I have married a woman and gave (her) gold equal to a date stone in
weight (as Mahr).”
