1- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ وَعَبْدِ الرَّحْمَنِ بْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ كَمِ الْمَهْرُ يَعْنِي فِي الْمُتْعَةِ قَالَ مَا تَرَاضَيَا عَلَيْهِ إِلَى مَا شَاءَ مِنَ الأجَلِ.
1. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr and ‘Abd al-Rahman ibn abu Najran from ‘Asem ibn Hamid from Muhammad ibn Muslim who has said the following: “In response to my question before abu ‘Abd Allah , 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.’”
