Tabi‘un
The Tabi‘un ( "followers") are the generation of Muslims who were born after the passing of the Prophet Muhammad but who were contemporaries of the Sahaba ("companions"). As such, they played an important part in the development of Islamic thought and philosophy, and in the political development of the early caliphate. The ones who came after the Tabi'un are called Tabi‘ al-Tabi‘in.
