In this episode Al Fadi and Bro. Mel discuss more titles that the Quran refers to that are Jewish; example 1. Jaloot /Galoot (Sura 2:251), which is a Jewish Exilarch; a Jewish leader of the diaspora.  2. Illiyun/ a reference to the Jerusalem Talmud. 3. Sijin (Sura 83:7) a reference to the Babylonian Talmud.  In the seventh century Mehmed was a Messianic title, and in the seventh century the Jews believed in two Messiahs ; Messiah bin Joseph( a suffering servant who dies for the Jews . the other is Messiah bin David who is a triumphant king who will destroy Israel's enemies. Also In the seventh century the Jews had a chain of Messiahs/ Mehmeds .  So could've the title Mehmed started as a historical name and with lots of distortions ended up being the Muhammad of Hijaz? Listen to hear the details.
