Sahih al-Bukhari · The Book of Al-Farad (The Laws of Inheritance)

26- بَابُ لاَ يَرِثُ الْمُسْلِمُ الْكَافِرَ وَلاَ الْكَافِرُ الْمُسْلِمَ، وَإِذَا أَسْلَمَ قَبْلَ أَنْ يُقْسَمَ الْمِيرَاثُ فَلاَ مِيرَاثَ لَهُ:

(26) Chapter. Neither a Muslim can be the heir of a disbeliever, nor a disbeliever can be the heir of a Muslim. And if somebody becomes a Muslim bfore the property of his dead (disbelievers) relative is divided among the heirs, he will have no share.
