When Mohammed escaped Medina, the Muslim community had just gotten there and understandably there were no mosques (as they had arrived within weeks). Mohammed, once there, constructed the Masjid an-Nabawi (the Prophet's Mosque) which remains the holiest site in Medina. It is likely that he built a few additional mosques as more people converted, but there are no exact figures.
The best estimate would be between 1-5.
Current Medina was called Yathrib during the time of Prophet Muhammad (S).
Abou Bakr was the prophet companion during his migration to Medina (Madinah in Arabic). Abou Bakr was the first Caliph (Muslim State ruler) after prophet Muhammad death in year 632 AD.
~Muhammad was his son-in-law. Abu Bakr was a close companion to Prophet Muhammad (PBUH) and the first man believed in Muhammad prophesy and accepting Islam religion. Abu was the only companion to Prophet Muhammad during his Immigration from Mecca (Makkah) to Medina. Abu Bakr is the father of Aisha, (may God be pleased with her) Prophet Muhammad wife. Abu Bakr was the 1st Caliph (Ruler) after prophet Muhammad death.
On arrival of prophet Muhammad (PBUH) to Medina coming from Makkah (Mecca) during Hijra in year 622 AD.
The Prophet (PBUH) went to Madina when the makkans were attempting to kill him, Madina was the first area to accept Islam fully.
The first mosque of Islam was built at the village of Quba by Prophet Muhammad during the migration to Yathrib ( Madinah )
In Islam, the first mosque was built by Muhammad in Quba, while he was travelling to Medina (Hijra). The first Friday prayer in Islamic history was also offered in this very mosque.
Muhammad was buried in his own house, which had already served as a mosque for some years. The mosque still lies there, and is counted as the second most important mosque in Islam, and Madina the second most holy city.
During the year when Prophet Muhammad lived.
Salah was made mandatory to Muslims during prophet Muhammad (PBUH) trip to the Heavens that is called the rising up (called in Arabic Al-Mi3raj). This was before prophet Muhammad (PBUH) migration (Hijra in Arabic) to Medina. It is the only Islam pillar that is commanded directly by God and not through the angel Gabriel (Jibril).
Some major events in Prophet Muhammad's life include receiving the first revelation from God through the Angel Gabriel, migrating from Mecca to Medina (known as the Hijrah), conquering Mecca, and delivering his farewell sermon during his last pilgrimage. These events were pivotal in shaping the development of Islam and the Muslim community.
There are no representations of prophet Muhammad (PBUH) adorning mosques for the following reasons:It is not allowed in Islam to have images or drawings for prophets any where.Mosque adorning should be within low limits in order not to distract Muslim attention during praying inside the mosque.Islam main principle is to worship God (Allah in Arabic) the one and only one God with no partner, son, father, companion, or any resemblance what so ever. Hence, any representations of prophet Muhammad adorning mosques are avoided to avoid by time paying excessive respect to these representations that my lead by time to some forms of polytheism or hanotheism.The representation of the prophet may not be real representation of the prophet but just according the imagination or the view of the artist as it was no photography at that time.The Prophet forbade anyone to make any likeness of him because other Prophets have been worshiped in the past. If we had a picture of Prophet to look at it would lead to worship in few future generations.
