كَتَبْتُ إِلَيْهِ[1] أَسْأَلُهُ عَنْ رَجُلٍ عَلَيْهِ مَهْرُ امْرَأَتِهِ لَا تَطْلُبُهُ مِنْهُ إِمَّا لِرِفْقٍ بِزَوْجِهَا وَ إِمَّا حَيَاءً فَمَكَثَ بِذَلِكَ عَلَى الرَّجُلِ عُمُرَهُ وَ عُمُرَهَا يَجِبُ عَلَيْهِ زَكَاةُ ذَلِكَ الْمَهْرِ أَمْ لَا فَكَتَبَ لَا يَجِبُ عَلَيْهِ الزَّكَاةُ إِلَّا فِي مَالِهِ.
“I once wrote to him (the Imam) (a.s.), about a man who owes Mahr of his woman who does not ask for payment due to sympathy or shyness. It goes on for their lifetime. Is he required to pay Zakat for that Mahr? He (the Imam) wrote, ‘Zakat is not due on him except for his assets.’”
