الْمَجُوسُ يَرِثُونَ بِالنَّسَبِ وَ لَا يَرِثُونَ بِالنِّكَاحِ الْفَاسِدِ فَإِنْ مَاتَ مَجُوسِيٌّ وَ تَرَكَ أُمَّهُ وَ هِيَ أُخْتُهُ وَ هِيَ امْرَأَتُهُ فَالْمَالُ لَهَا مِنْ قِبَلِ أَنَّهَا أُمٌّ وَ لَيْسَ لَهَا مِنْ قِبَلِ أَنَّهَا أُخْتٌ وَ أَنَّهَا زَوْجَةٌ شَيْءٌ.
The Magians (Zoroastrians) inherit through blood relations but not through invalid marriage. So, if a Magian man dies and leaves behind his mother, who is also his sister and his wife, the inheritance goes to her because she is his mother. However, she does not inherit anything by virtue of being his sister or his wife.
