“Once ‘Abd Allah ibn ‘Umayr al-Laythiy came to abu Ja‘far (a.s.), and asked, ‘What do you say about al-Mut‘ah (advantageous marriage) of women?’ He (the Imam) said, ‘Allah has made it lawful in His book by the tongue of His Holy prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, thus it will remain lawful up to the Day of Judgment.’ He then said, ‘O abu Ja’far, how can someone like you say this, when ‘Umar made it unlawful and prohibited it?’ He (the Imam) said, ‘Even if he has done so.’ He said, ‘I ask Allah to protect you against a thing that ‘Umar has made unlawful.’ He (the narrator) has said that he (the Imam) then said, ‘So you can stand by the words of your friend but I stand by the words of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, and I am prepared for al-Mula‘inah (ask Allah to condemn the party on the side of falsehood) that the word is what the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said; and that falsehood is what your friend has said.’ He (the narrator) has said that ‘Abd Allah ibn ‘Umayr then said, ‘Will it make you happy that your women, daughters, sisters, daughters of your aunts do?’ He (the narrator) has said that abu Ja‘far (a.s.), when he mentioned his women and daughters of his aunts turned away from him.’”
