Sura al-Anfāl 8:72

إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَهَاجَرُوا۟ وَجَٰهَدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّـهِ وَٱلَّذِينَ ءَاوَوا۟ وَّنَصَرُوٓا۟ أُو۟لَٰٓئِكَ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍ وَٱلَّذِينَ ءَامَنُوا۟ وَلَمْ يُهَاجِرُوا۟ مَا لَكُم مِّن وَلَٰيَتِهِم مِّن شَىْءٍ حَتَّىٰ يُهَاجِرُوا۟ وَإِنِ ٱسْتَنصَرُوكُمْ فِى ٱلدِّينِ فَعَلَيْكُمُ ٱلنَّصْرُ إِلَّا عَلَىٰ قَوْمٍۭ بَيْنَكُمْ وَبَيْنَهُم مِّيثَٰقٌ وَٱللَّـهُ بِمَا تَعْمَلُونَ بَصِيرٌ

Those who believed, and adopted exile, and fought for the Faith, with their property and their persons, in the cause of Allah, as well as those who gave (them) asylum and aid,- these are (all) friends and protectors, one of another. As to those who believed but came not into exile, ye owe no duty of protection to them until they come into exile; but if they seek your aid in religion, it is your duty to help them, except against a people with whom ye have a treaty of mutual alliance. And (remember) Allah seeth all that ye do.

Sura al-Qaṣaṣ 28:18

فَأَصْبَحَ فِى ٱلْمَدِينَةِ خَآئِفًا يَتَرَقَّبُ فَإِذَا ٱلَّذِى ٱسْتَنصَرَهُۥ بِٱلْأَمْسِ يَسْتَصْرِخُهُۥ قَالَ لَهُۥ مُوسَىٰٓ إِنَّكَ لَغَوِىٌّ مُّبِينٌ

fa-aṣbaḥa fī l-madīnati khāʾifan yataraqqabu fa-idhā alladhī astanṣarahu bil-amsi yastaṣrikhuhu qalā lahu mūsā innaka laghawiyyun mubīnun
