The Id-ul-Zoha or Bakr-Id festival of the Muhammadans is such a rite.

In pre-Islamic times this sacrifice was held at Mecca and all the Arab tribes went to Mecca to celebrate it.

The month in which the sacrifice was held was one of those of truce, when the feuds between the different clans were in abeyance so that they could meet at Mecca.

Muhammad continued the sacrifice of the Id-ul-Zoha and it is this sacrifice which a good Muhammadan takes the pilgrimage to Mecca to perform.

He must be at Mecca on the tenth day of the month of Z'ul Hijjah and perform the sacrifice there, and unless he does this there is no special merit in making the journey to Mecca.
