Islam is a Semitic religion, which has over one billion adherents all over the world. Islam means "submission to the will of God". Muslims accept the Qur’an, as the word of God revealed to His last and final prophet, Muhammad (peace be upon him). Islam states that Allah sent messengers and prophets throughout the ages with the message of Unity of God and accountability in the Hereafter. Islam thus makes it an article of faith to believe in all the earlier prophets, starting with Adam, and continuing with Noah, Abraham, Ishmael, Isaac, Jacob, Moses, David, John the Baptist and Jesus amongst many others (may peace be on them all).
Islam has existed all along from the beginning and will continue to exist till Doomsday. The true name of the religion of all men who submit to the Will of Allâh is Islam and all those who follow this faith are Muslims. Thus all the prophets of God including Adam, Noah, Abraham, Jacob, Joseph, David, Solomon, Moses and Jesus (Peace be upon them) were Muslims and the religion they believed in was Islam. Muslims believe that Muhammad (Peace and Blessings be upon him) was the last, not the only prophet of Allâh. They believe in all the prophets who came before Prophet Muhammad (Peace and Blessings be upon him). They believe that all those prophets of God and all their faithful followers were Muslims and that their religion was Islam. Therefore, just like the followers of Prophet Muhammad (Peace and Blessings be upon him), the true followers of Abraham, Moses, Jesus, and all the other messengers of God (Peace be upon them all) were Muslims.
" The same religion has He established for you as that which He enjoined on Noah that which We have sent by inspiration to thee and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein: to those who worship other things than Allâh. "
[The Qurân Ch: 42 Al-Shura, V: 13]
A fascinating experience - within a few days of each other, I was given some info brochures on Muslim customs, culture, and theology and on Jehova's Witness customs, culture, theology. It's interesting to compare them - they take completely opposite approaches to educating people about their faiths.
I snapped a couple of pictures of each. I think these are pretty representative pictures -
