Islamic unity and solidarity according to the Quran and Nahj Al- Balaqa

The present paper assesses terminology of ''unity and solidarity'' and then analyses various types of unity according to the Quran and Nahj Al-Balaqa. According to sociology, unity in religion is divided into three types: first, unity in societies, second, unity in the field of Ibrahimic religions, and third, Islamic unity. This paper intends to study Islamic unity. In Islamic unity, the author deals with the principles and major factors of unity; such as monotheism, Islam, the Quran, the Prophet of Islam (s.a), love of Ahl-e Bayt (a.s), Islamic brotherhood, Muslim's Qiblah and Hajj pilgrimage. Also the paper assesses major ways for achieving Islamic unity; e.g. boosting commonalities, tolerating other's belief, critiquing without disrespecting, academic exchange between Muslim scholars, refraining from fanaticism, promoting Islamic unity, and having good will for each other. Such issues are assessed based on the teachings of the Quran and Nahj Al-Balaqa. Other issues assessed in this paper based on the Quran and Nahj Al-Balaqa include the outcome of Islamic unity such as security, dignity, religious power, national solidarity and honor, growth of Islamic society, and increase in divine blessings.
