Islam and Christianity have a lot in common because they originate from a single source. Abraham is believed to be the source from which Islam, Christianity and Judaism took roots and this is one of the reasons why these religions are also known as Abrahamic religions. Due to their common origins, the scriptures of birth Islam and Christianity have a lot in common and at the same time, they also differ in a few aspects.

So, Bible contains words chosen and written by human beings that would make it easy for other people to read and understand. In other words, it was mediated by God through human beings to ensure that others can relate to it and accept it easily.

Islam, on the other hand, believes that the Qur'an does not have any human hand to it. The prophet Mohammed was believed to be illiterate and he simply repeated the words that God told him. In fact, the word Qur'an means recitation and it is believed that Mohammed simply recited what God told him.
