Brotherhood (ukhuwwah) is the foundation of the unity of mankind in a society entity. A person's image and heart depend not on his race, color, ancestry, rank, or property, but are measured based on the height of commendable character. Within the framework of this fraternity, social interaction among people should follow the manners outlined by Islam. To reflect the brotherhood according to the boundaries of syara', the concept of brotherhood should be based on a noble and steady bond of faith. The neglect of these rights will lead to disagreements, disputes and sever ties between Muslims. Thus, this study was conducted to analyze the concept of brotherhood and friendship in Islam as well as to see how this spirit of brotherhood and friendship can be applied in the day of Muslims. This study focuses on the study of document analysis which is to look at the interpretation of the Quran and the snippets of hadiths as well as past studies related to brotherhood and friendship. The results of the study found that there are various forms of brotherhood and friendship rights that have been recommended by Islam to ensure that the relationship between a Muslim and another Muslim is built such as rights in the field of property, the right to provide assistance to the soul and body, the right to preserve the tongue and heart, the right to preserve speech, the right to give a living, the right to pray for friends, the right to keep promises and to be sincere and the right to provide facilities. By exercising all the rights of such brotherhood and friendship in life, it is certain that the Muslim community can avoid disagreements between Muslims and continue to remain in harmony and well-being in line with the preservation of the civil society dreamed of under the umbrella of Rahmat Allah SWT.
