Hadith.4585 - Al-Hasan ibn Mahbub narrated from Aban, from Abu Maryam, from Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) who was asked about Mutah (temporary marriage).

"Mutah today is not as it was before. In those days, women were trustworthy, but today they are not trustworthy, so inquire about them."
