Surat Al Anfal: (73-74)

{وَالَّذينَ كَفَرُواْ بَعْضُهُمْ أَوْلِيَاء بَعْضٍ إِلاَّ تَفْعَلُوهُ تَكُن فِتْنَةٌ فِي الأَرْضِ وَفَسَادٌ كَبِيرٌ} [الأنفال : 73]

73- Disbelievers are guardians to one another in support and inheritance. The majority of scholars hold the view that a Muslim does not inherit from a disbeliever and a disbeliever does not inherit from a Muslim. If you do not show hostility to polytheists, befriend the believers, and follow the instructions set by Allah in regard to inheritance, things will be mixed between believers and disbelievers, the power of disbelievers shall be apparent, Islam will become weak, and blood shall be shed.

{وَالَّذِينَ آمَنُواْ وَهَاجَرُواْ وَجَاهَدُواْ فِي سَبِيلِ اللّهِ وَالَّذِينَ آوَواْ وَّنَصَرُواْ أُولَـئِكَ هُمُ الْمُؤْمِنُونَ حَقّاً لَّهُم مَّغْفِرَةٌ وَرِزْقٌ كَرِيمٌ} [الأنفال : 74]

74- And those who believed, left their homes and money to escape disbelieve and disbelievers to Islam, and fought the disbelievers with you as well as the Supporters who aided and sheltered their Muslim Migrants are the true believers. They shall be rewarded generously by their Lord by forgiving their sins, providing them permanent sustenance, and they shall reside in a high Paradise and everlasting bliss.
