Mahr (dower) in this form of Marriage, al-Mut‘ah

1. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr and ‘Abd al-Rahman ibn abu Najran from ‘Asem ibn Hamid from Muhammad ibn Muslim who has said the following: “In response to my question before abu ‘Abd Allah عليه السلام, about how much mahr (dower) is - in al-Mut‘ah (advantageous marriage), he (the Imam) said, ‘It is whatever they agree on, up to the time they want.’”
