Beware false prophets!
Islam religion is practiced today the same way it was practiced in time of prophet Muhammad (PBUH). Quran and Sunnah (prophet Muhammad sayings and practices) are valid anywhere any time until the Day of Resurrection. Refer to related question below on Islam teachings.
Shia (meaning followrs of Ali) and sunni (meaning who behaves same as behaviors of prophet)
Yathrib is better known today as Medina. It is known as the "City of the Prophet" because it was the city that Prophet Muhammad migrated to from Mecca in 622 CE, a significant event in the history of Islam. Medina holds great religious significance for Muslims as it is the second holiest city in Islam after Mecca.
The prophet Muhammad is the founder of the religion of Islam and the primary author of the sacred scripture the Quran. There are approximately 1 billion Muslims (followers of Islam) in the world today.
Islam itself ultimately has been around since the beginning of mankind because islam translates as "Submission to the will God(one)". Most religions began as Islam-submission to ONE God, but over time were changed and corrupted. The Islam we know today-revealed by the Prophet mohammad, began in Saudi Arabia.
The Prophet Muhammad peace be upon him is extremely important, his teachings his life his morals his struggles, hadiths(sayings), make up the Sunnah that Muslims follow today because he was the best example and an amazing prophet._________________________________________________In addition to the above:God founded the religion of Islam. Refer to question below.Quran; that reflects real God words revelation to prophet Muhammad (PBUH); plus prophet Muhammad sayings and practices, played the basic role in the development of Islam religion.
salam... prophet Muhammad is the last prophet. during israk mikraj all the prophet are meet together, they give salam to each other. finally they pray which we pray now today in Muslim and prophet Muhammad are the leader in that pray (solat) which call imam. in this case, prophet Muhammad was stand in front of all the other prophet, included prophet Jesus. that why all the Muslim today much more praised prophet Muhammad and he is the last prophet. that mean we now is the follower of prophet Muhammad. not Jesus. who ever follow prophet Jesus, call them self christian. Actually Christians are not resist. they are spouse joint Muslim and become Islam. Why this happen, the answer is because Israel and Nasrani (the Israel helper, what I seen today is America) jealousy at Muslim and Islam. Prophet Muhammad said, don't harm any body and be a friend to any body include your enemies. That why we didn't have a weapon to fight now, cause we are friendly to any body but Israel and hie helper try to sabotage Muslim and say Muslim is terrorism. Its not true. Hundred percent wrong. Wassalam.....
Muhammad is the founder of the religion known as Islam. According to Muslims (the believers), Muhammad received his revelation from God, and revealed what was later to become the Quran.
People who follow Islam today are called Muslims. They were still called Muslims in Prophet Muhammad's (pbuh) time, but his community of faithful were also called the ummah.
according to Islam God sent 124000 prophet during all the history and all of them are not known today. some of who not mentioned in Koran according to sayings of prophet and 12 Imams are: Hezghil Ishmuil Ermia (Aziz) Khizr Shaiya Highough Daniel Jeorjis Hanzaleh Khalid
Muslims are not an android system that developed over the years. They are people who believe in omnipotence and consider the Holy Prophet Muhammad PBUH as the final messenger upon whom the Quran was revealed. They then expanded to this level that even today Islam is the worlds fastest growing religion.
