The holy Qur’an was revealed to Prophet Mohammad (SAWA) over a period of 23 years for the guidance of all humanity. The Prophet practically demonstrated how to live in peace and harmony, by obeying the commandments of God, abstaining from sins, and striving for material development and spiritual perfection. Following the passing away of Prophet Mohammad (SAWA), discord and disputes emerged. In other words, despite God’s commandments Islamic unity and brotherhood was badly damaged by the actions of certain elements. Ayah 10 of Surah Hujurat says:
"The faithful are indeed brothers. Therefore make peace between your brothers and be wary of Allah, so that you may receive [His] mercy."
