Al-Anfal 8:74

وَإِن يُرِيدُوا خِيَانَتَكَ فَقَدْ خَانُوا اللَّهَ مِن قَبْلُ فَأَمْكَنَ مِنْهُمْ ۗ وَاللَّهُ عَلِيمٌ حَكِيمٌ

But if they intend to betray you - then they have already betrayed Allah before, and He empowered [you] over them. And Allah is Knowing and Wise.

إِنَّ الَّذِينَ آمَنُوا وَهَاجَرُوا وَجَاهَدُوا بِأَمْوَالِهِمْ وَأَنفُسِهِمْ فِي سَبِيلِ اللَّهِ وَالَّذِينَ آوَوا وَّنَصَرُوا أُولَـٰئِكَ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ وَالَّذِينَ آمَنُوا وَلَمْ يُهَاجِرُوا مَا لَكُم مِّن وَلَايَتِهِم مِّن شَيْءٍ حَتَّىٰ يُهَاجِرُوا ۚ وَإِنِ اسْتَنصَرُوكُمْ فِي الدِّينِ فَعَلَيْكُمُ النَّصْرُ إِلَّا عَلَىٰ قَوْمٍ بَيْنَكُمْ وَبَيْنَهُم مِّيثَاقٌ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ

Indeed, those who have believed and emigrated and fought with their wealth and lives in the cause of Allah and those who gave shelter and aided - they are allies of one another. But those who believed and did not emigrate - for you there is no guardianship of them until they emigrate. And if they seek help of you for the religion, then you must help, except against a people between yourselves and whom is a treaty. And Allah is Seeing of what you do.

وَالَّذِينَ كَفَرُوا بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۚ إِلَّا تَفْعَلُوهُ تَكُن فِتْنَةٌ فِي الْأَرْضِ وَفَسَادٌ كَبِيرٌ

And those who disbelieved are allies of one another. If you do not do so, there will be fitnah on earth and great corruption.

وَالَّذِينَ آمَنُوا مِن بَعْدُ وَهَاجَرُوا وَجَاهَدُوا مَعَكُمْ فَأُولَـٰئِكَ مِنكُمْ ۚ وَأُولُو الْأَرْحَامِ بَعْضُهُمْ أَوْلَىٰ بِبَعْضٍ فِي كِتَابِ اللَّهِ ۗ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ

And those who believed after [the initial emigration] and emigrated and fought with you - they are of you. But those of [blood] relationship are more entitled [to inheritance] in the decree of Allah. Indeed, Allah is Knowing of all things.
