The Qur'an has been translated into most major African, Asian and European languages from Arabic.

Salman al-Farsi was a Persian religious scholar and one of the companions of Muhammad. As a practicing Zoroastrian, he dedicated much of his early life to studying to become a magus, though he later became preoccupied with travelling throughout Western Asia to engage in interfaith dialogue with other religious groups. His quests eventually prompted his conversion to Christianity and later his conversion to Islam, which occurred after he met and befriended Muhammad in the city of Yathrib. He was a prominent non-Arab companion and one of Muhammad's closest friends; Muhammad had once stated to a gathering of his followers that he regarded Salman as a part of his family. In meetings with the other companions, he was often referred to by the kunya Abu ʿAbdullah.
