Farewell Pilgrimage
The Farewell Pilgrimage (Arabic: حِجَّة ٱلْوَدَاع, romanized: Ḥijjat al-Wadāʿ) refers to the one Hajj pilgrimage that Muhammad performed in the Islamic year 10 AH, following the Conquest of Mecca. Muslims believe that verse 22:27 of the Quran brought about the intent to perform Hajj in Muhammad that year. When Muhammad announced this intent, approximately 100,000 of his Sahaba gathered in Medina to perform the annual pilgrimage with him. Muhammad performed Hajj al-Qiran.
According to the opinion of Sunnis, Hajj al- Qirān is type of Hajj in which Umrah and Hajj are performed together. On the 9th of Dhu al-Hijjah, the Day of Arafah, Muhammad delivered the Farewell Sermon atop the Mount Arafat outside Mecca.
Muhammad's pilgrimage defined several of the rituals and rites of the Hajj and is one of the most well-recorded moments of his life, later transmitted through his sahaba, who accompanied him on this occasion, observing every gesture of Muhammad, which has become a precedent to be followed by Muslims all over the world (sunnah).
