The Prophet’s Mosque, the second holiest site in Islam, is one of the largest mosques in the world. It was built by the Prophet Muhammad, may the mercy and blessings of God be upon him, after his migration to Al Madinah in 622 AH. The Prophet bought the land - that was located besides his home - from two orphan boys. He then built the mosque from the branches and stems of the local date palm trees. The mosque, that had a height of approximately 50 meters and a similar width, was partially roofed. It had an area at the back designated for travellers and the needy.
