Rashidun

The Rashidun (Arabic: الراشدون, romanized: al-Rāshidūn, lit. 'the rightly-guided') are the first four caliphs (lit.: 'successors') who led the Muslim community following the death of Muhammad: Abu Bakr (r. 632–634), Umar (r. 634–644), Uthman (r. 644–656), and Ali (r. 656–661).

The reign of these caliphs, called the Rashidun Caliphate (632–661), is considered in Sunni Islam to have been 'rightly guided' (Arabic: rāshid), meaning that it constitutes a model (sunna) to be followed and emulated from a religious point of view.
