Shortly after Muhammad's death the Quran was compiled into a single book by order of the first Caliph Abu Bakr and at the suggestion of his future successor Umar. Hafsa, Muhammad's widow and Caliph Umar's daughter, was entrusted with that Quranic text after the second Caliph Umar died.[11] When the third Caliph Uthman began noticing slight differences in pronunciation of the Qur'anic Arabic by those whose dialect was not that of the Quraish, he sought Hafsa's permission to use her text and commissioned a committee to produce a standard copy of the text of Qur'an to which added diacritical marks ensured correct pronunciation, and to be set as the standard dialect, the Quraish dialect, now known as Fus'ha (Modern Standard Arabic) (see Origin and development of the Qur'an).

In the Hebrew Bible a messiah (or mashiach) is a king or High Priest traditionally anointed with holy anointing oil.

The Christian concept of the Christ/Messiah as "the Word made Flesh" (see also Logos) is fundamentally different from the Jewish and Islamic. The majority of historical and mainline Christian theologies, as seen within the Nicene Creed, consider Jesus to be God or God the Son.

Islamic tradition holds the view that Isa, son of Maryam (aka Jesus, son of Mary), was the promised nabi (Prophet) and masih (Messiah) sent to the Israelites, and that he will again return to Earth in the end times, along with al-Mahdi, and they will defeat Masih ad-Dajjal (lit. "false Messiah"; cf. antichrist)Islamic tradition holds the view that Isa, son of Maryam (aka Jesus, son of Mary), was the promised nabi (Prophet) and masih (Messiah) sent to the Israelites, and that he will again return to Earth in the end times, along with al-Mahdi, and they will defeat Masih ad-Dajjal (lit.
