سَأَلْتُ أَبَا عَبْدِ اللَّهِ ع كَمِ الْمَهْرُ يَعْنِي فِي الْمُتْعَةِ قَالَ مَا تَرَاضَيَا عَلَيْهِ إِلَى مَا شَاءَ مِنَ الْأَجَلِ.
“In response to my question before abu ‘Abd Allah (a.s.), 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.’”
