“This is concerning my question before abu ‘Abd Allah (a.s.), about the case of al-Nasib (one hostile to ‘A’immah) who is well known for his hostility; if we can give a believing woman in marriage to him. He (the guardian of the believing woman) is capable to disprove his (Nasib’s) belief but he (Nasib) is not able to prove himself right. He (the Imam) said, ‘A believing man must not marry a Nasibah and a believing woman must not be given in marriage to him and a believing woman must not marry a man of weak understanding.’”
