Had they gone forth with you, they would not have increased you except in confusion, and they would have been active among you, seeking [to cause] you fitnah [i.e., chaos and dissension]. And among you are avid listeners to them. And Allāh is Knowing of the wrongdoers. (Surah At-Tawbah, 9:47)

قُل لِّعِبَادِيَ الَّذِينَ آمَنُوا يُقِيمُوا الصَّلَاةَ وَيُنفِقُوا مِمَّا رَزَقْنَاهُمْ سِرًّا وَعَلَانِيَةً مِّن قَبْلِ أَن يَأْتِيَ يَوْمٌ لَّا بَيْعٌ فِيهِ وَلَا خِلَالٌ ٣١

خِلَالٌ khilālun · any friendship

[O Muḥammad], tell My servants who have believed to establish prayer and spend from what We have provided them, secretly and publicly, before a Day comes in which there will be no exchange [i.e., ransom], nor any friendships. (Surah Ibrahim, 14:31)

وَمَنْ أَحْسَنُ دِينًا مِّمَّنْ أَسْلَمَ وَجْهَهُ لِلَّهِ وَهُوَ مُحْسِنٌ وَاتَّبَعَ مِلَّةَ إِبْرَاهِيمَ حَنِيفًا وَاتَّخَذَ اللَّهُ إِبْرَاهِيمَ خَلِيلًا ١٢٥

خَلِيلًا khalīlan · (as) a friend

And who is better in religion than one who submits himself to Allāh while being a doer of good and follows the religion of Abraham, inclining toward truth? And Allāh took Abraham as an intimate friend. (Surah An-Nisa, 4:125)

يَا أَيُّهَا الَّذِينَ آمَنُوا أَنفِقُوا مِمَّا رَزَقْنَاكُم مِّن قَبْلِ أَن يَأْتِيَ يَوْمٌ لَّا بَيْعٌ فِيهِ وَلَا خُلَّةٌ وَلَا شَفَاعَةٌ وَالْكَافِرُونَ هُمُ الظَّالِمُونَ ٢٥٤

خُلَّةٌ khullatun · friendship

O you who have believed, spend from that which We have provided for you before there comes a Day in which there is no exchange [i.e., ransom] and no friendship and no intercession. And the disbelievers - they are the wrongdoers. (Surah Al-Baqarah, 2:254)
