The Treaty of al-Hudaybiya (Arabic: صُلح الْحُدَيْبِيَة, romanized: Ṣulḥ al-Ḥudaybiya) was an event that took place during the lifetime of the Islamic prophet Muhammad. It was a pivotal treaty between Muhammad, representing the state of Medina, and the tribe of the Quraysh in Mecca in March 628 (corresponding to Dhu al-Qi'dah, AH 6). The treaty helped to decrease tension between the two cities, affirmed peace for a period of 10 years, and authorised Muhammad's followers to return the following year in a peaceful pilgrimage, which was later known as the First Pilgrimage.
