It was narrated that: Abu Salamah said: “I asked Aishah: 'How much was the dowry of the wives of the Prophet?' She said: 'The dowry he gave to his wives was twelve Uqiyyah and a Nash (of silver). Do you know what a Nash is? It is one half of an Uqiyyah. And that is equal to to five hundred Dirham.' ”
