One of the strongest and most deep-rooted links in human relations, is the tie of brotherhood. Brothers love each other, are benevolent towards each other, and share each other's joys and sorrows. Sometimes differences may occur between brothers, causing anxieties, but very soon these acrimonies are replaced by affection and sincerity, and rifts completely forgotten. Islam makes use of this firm link in order to strengthen social order and ameliorate human relations, and considers all devout Muslims as true brothers. As two brothers are joined together through their father, the Seal of the prophets is regarded as a father of the Ummah in Islam, and the Muslims as his children. In this way, all the Muslims have been considered as brothers. In this verdict, namely Islamic brotherhood, there exists no boundary, and all Muslims from any race, locality and language are covered by this law, and are regarded as brothers by Islam.
