1. Muḥammad ibn Yaḥyā narrated from Aḥmad ibn Muḥammad, from Ibn Faḍḍāl, from Ibn Bukayr, from Muḥammad ibn Muslim, who said: "I heard Abū Jaʿfar al-Baqir (as) say regarding a man who marries a woman through mutʿah (temporary marriage): They will inherit from each other unless they make a stipulation (to the contrary). Indeed, the stipulation is made after the marriage."

2. Ali ibn Ibrahim has narrated from his father from Ahmad ibn Muhammad from ibn abu Nasr who has said the following: “Abu al-Hassan al-Rida’ (a.s.), has said, ‘Marriage in the manner of al-Mut‘ah (advantageous marriage) can be with or without inheritance. There is inheritance if it is stipulated; and there is not any inheritance if it is not stipulated.’ It also is narrated that there is not any inheritance no matter a condition is set or is not set.’”
