Ahmad ibn Muhammad has narrated from al-Husayn ibn Sa‘id from Hammad ibn ‘Isa from Shu’ayb ibn Ya’qub from abu Basir who has said the following: “I once asked abu Ja‘far (a.s.), about al-Mut‘ah (advantageous marriage) of women. He (the Imam) said, ‘It is lawful and one dirham or more is enough (as mahr (dower)).”’
