أمير المؤمنين
"Mawla" has a number of meanings in Arabic, with interpretations of Muhammad's use here being split along sectarian lines between the Sunni and Shia. Among the former group, the word is translated as "friend" or "one who is loyal/close" and that Muhammad was advocating that Ali was deserving of friendship and respect. Conversely, Shi'ites tend to view the meaning as being "master" or "ruler" and that the statement was a clear designation of Ali being Muhammad's appointed successor. Shia sources also record further details of the event, such as stating that those present congratulated Ali and acclaimed him as "Amir al-Mu'minin".
