The two plurals إِخْوَة and إِخْوَان generally refer to brothers by blood ties and brothers by companionship or friendship respectively. In this respect, note the rhetorical use of the former plural in the Quranic verse إِنّمَا الْمُؤْمِنُونَ إِخْوَةٌ The believers are but brothers, suggesting that the ties of brotherhood between the believers should be like the ties between blood brothers.
