Abu Salama said he asked ‘A’isha how much the Prophet had given as dower, and she replied that his dower to his wives was twelve uqiyas* and a nashsh. She asked whether he knew what a nashsh was, and when he replied that he did not, she said it was half an uqiya; so the total was five hundred dirhams. * The uqiya was 40 dirhams. Muslim transmitted it. Nashsh is in the nominative in Sharh as-sunna and all the sources.
