At the time the treaty was signed the Muslims could not have foreseen that the number of people who would travel to Medinah to become Muslims in the following year would be greater than in all the years before. Before the Muslims departed, they followed the Prophet's example of making sacrifice and either shaving or cutting their hair. Even though they were unable to visit the sacred mosque, their pilgrimage was accepted by Allah because it had been their true intention.
On the return journey to Medinah,the 'Victory' chapter of the Koran was revealed to the Prophet (pbuh). It begins:
A year after the signing of the Treaty of Hudaybiyah, the Prophet (pbuh) was able to lead two thousand pilgrims on the 'Umra. Quraysh vacated Mecca and watched the rites from the hills above the city. The agreed period of three days was observed, after which the Muslims returned to Medinah.
