The majority of people in Medina (or AlMadinah) accepted the Islam religion even before the migration of prophet Muhammad (peace be upon him) to Medina in the year 623 AD. This is why the prophet was very much welcomed when he arrived to Medina.
Mohammad did not head to Makkah, instead he went to Medina from Makkah, because the people in Makkah had made his living there ( in Makkah) very difficult
My guess is learn about his social life and to show how much we care about mohammad.
No one can invent a religion, but it could be founded by someone. According to history,Islam was founded by Muhammad(the last prophet) he had spread the idea of Islam to people in Makkah, but many people who converted to Islam there were persecuted. So Muhammad and some of his followers traveled to Yathrib and later was called Medina. Many people in Medina converted to Islam.
It was name given to him due to honesty by people of Makkah .
Islam is not focused on any religion. The Holy Qoran was revealed to Prophet Mohammad as a Scripture from Allah (God) for the people of this world. The followers of this Book and the teachings of the Prophet Mohammad are called Muslims, and the religion is known as Islam.
Prophet Mohammad Prayed, fasted did many miracles such as write the book of Allah and he stopped most people do many bad harm things.
Mohammed created the first Islamic City State in Medina and wrote the Constitution of Medina, giving specific rights and duties to the various Jewish Arab and Pagan Arab tribes in addition to the Muslims.
Mostly the Jews. Some of the people who were under the influence of Abdullah bi Ubie, the chief of the hypocrites.
The Prophet (P.B.U.H) migrated to Medina because in Mecca he was tortured, both physically and mentally by the people living there. Through the"Pledges Of Aqabah" he found out that the people of Medina were more friendly towards him and wanted him to be their leader. The migration enabled the Muslims to worship freely and from Medina Islam spread rapidly.
No Prophet Muhammad (PBUH) is no God of Islam or anything else. Prophet Muhammad is God messenger who conveyed to mankind Quran per God revelation to him through the angel Gabriel (Jibril) and called people to Islam.
The 5 prayers were ordained in the Night journey to Heaven in 621 AD when Prophet Mohammad (SAW) was taken to Heaven to see The Almighty God, and on his return he was given 50 daily prayers for the people. On the way back the Prophet met Prophet Moses (PUH) who said that it will be too much for the people and requested Prophet Mohammad to go back and ask for reduction in the number of prayers. After a few repeated visits it was reduced to 5 prayers per day
