٥- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنْ عَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما السَّلام) فِي الرَّجُلِ يَقُولُ لِعَبْدِهِ أُعْتِقُكَ عَلَى أَنْ أُزَوِّجَكَ ابْنَتِي فَإِنْ تَزَوَّجْتَ أَوْ تَسَرَّيْتَ عَلَيْهَا فَعَلَيْكَ مِائَةُ دِينَارٍ فَأَعْتَقَهُ عَلَى ذَلِكَ وَتَسَرَّى أَوْ تَزَوَّجَ قَالَ عَلَيْهِ شَرْطُهُ.
5. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “About the case of a man who has a slave to whom he says, ‘I set you free with the condition that I will give my daughter in marriage to you and if you married a second wife on her or did something secretly against her you must pay one hundred dinar’, and he sets him free on such condition but he does secretly and marries. One of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, has said, ‘He must stand by his condition.’”
