وَ رَوَى إِسْمَاعِيلُ بْنُ أَبِي زِيَادٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَلَيْهِ اَلسَّلاَمُ أَنَّ عَلِيّاً عَلَيْهِ اَلسَّلاَمُ قَالَ: "لاَ يَحِلُّ اَلنِّكَاحُ اَلْيَوْمَ فِي اَلْإِسْلاَمِ بِإِجَارَةٍ بِأَنْ يَقُولَ أَعْمَلُ عِنْدَكَ كَذَا وَ كَذَا سَنَةً عَلَى أَنْ تُزَوِّجَنِي أُخْتَكَ أَوِ اِبْنَتَكَ" قَالَ "هُوَ حَرَامٌ لِأَنَّهُ ثَمَنُ رَقَبَتِهَا وَ هِيَ أَحَقُّ بِمَهْرِهَا".
Ismail ibn Abi Ziyad narrated from Imam Jafar ibn Muhammad Al-Sadiq (a.s) from his father, Imam Muhammad ibn Ali Al-Baqir (a.s) that Imam Ali ibn Abi Talib (a.s) said: "Marriage through employment is not permissible in Islam today, such as when someone says, 'I will work for you for such and such a year in exchange for marrying your sister or daughter.' Such an arrangement is forbidden because it reduces her to a price, whereas she is entitled to her dowry."
