Treaty of Hudaybiyyah
Diplomatic negotiations were pursued once the Islamic prophet Muhammad refused to use force to enter Mecca, out of respect to the Holy Ka'aba. In March, 628 CE (Dhu'l-Qi'dah, 6 AH), the Treaty of Hudaybiyyah was drawn up and signed, with terms stipulating a ten-year period free of hostilities, during which the Muslims would be allowed a three-day-long access per year to the holy site of the Ka'aba starting the following year. On the year it was signed, the followers of Mohammed were forced to return home without having performed Umrah.
