Muhammad's return was followed by several battles which led to Muslims conquering the rest of Arabia, and a final return to Mecca in 632 where he completed his first true Islamic pilgrimage, and made his Farewell Sermon at Mount Arafat. His return marked the end of the tenth year after Muslims' migration to Medina, and his pilgrimage set the precedence for the annual Great Pilgrimage, known as Hajj. In his Farewell Sermon, at Mount Arafat east of Mecca on the 9th of Dhu al-Hijjah, Muhammad advised his followers not to follow certain pre-Islamic customs, and generally exhorted Muslims to follow the teachings that he had set forth in the Quran and sunnah.
