It was narrated from ‘Amr bin Shu’aib, from his father, from his grandfather, that the Messenger of Allah ﷺ said:
“People of two different religions do not inherit from one another.”

حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا ابْنُ لَهِيعَةَ، عَنْ خَالِدِ بْنِ يَزِيدَ، أَنَّ الْمُثَنَّى بْنَ الصَّبَّاحِ، أَخْبَرَهُ عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " لاَ يَتَوَارَثُ أَهْلُ مِلَّتَيْنِ " .
