Islam = give in and obey the will of Allah.
Allah had made us and therefore knows what is good and bad for us, and by following Islam totally, we will be at peace with ourselves.
Islam is not like other religions, which are named either by the person who found the religion, or the land where the religion first came about.
E.g.1: Judaism is named after the tribe Judea of the land by the same name.
E.g.2: Christianity is named after Christ (Prophet Isa).
Islam is not named after Prophet Muhammad (S) because we do not believe that he was the founder of Islam. Islam is the religion of Allah. Allah says in the Holy Qur'an in: Sura Ali Imran verse 19:
"Indeed the religion with Allah is Islam." (3:19)
Islam is the only religion taught by all 124,000 Prophets, from Prophet Adam to Prophet Muhammad (S).
The basic teachings of all of the Prophets were the same, but the laws of religion were different depending on the time of the Prophet and the understanding of the people of that time.
E.g.: First, we had Microsoft Windows '95, and then as the understanding of people increased we got an upgrade to Windows '98, where although the initial idea was the same, there were more functions and in the same way we progressed until now when we have Windows 7.
Those who upgrade get the full benefit of the program but those who remain with Windows '95, get the initial benefit only.
In this same way the Prophets all taught that there is one God and that they were His Prophets. However, the rules of the religion came as and when Allah thought the people were ready understand.
Finally, the complete religion of Islam was sent to the world, through Prophet Muhammad (S); And those who followed are getting the full benefit of the religion.
