In 1237 Henry Bodrugan received the grant of a market on Fridays and a fair at Michaelmas in his manor of Pendrym.
The corn market, held on Fridays, is of remote origin.
Besides Wednesdays and Fridays, there are four fasting seasons, Lent, Pentecost to SS.
In the Anglican Church, the " days of fasting or abstinence " are the forty days of Lent, the Ember days, the Rogation days, and all the Fridays in the year, except Christmas day.
The larger mosques have two imams: one is called (in Arabia and Egypt) the khatib, and he preaches the sermon on Fridays (the Moslem Sabbath); the other, the ratib, reads the Koran, and recites the five daily prayers, standing close to the mihrab, and leading the congregation, who repeat the prayers with him, and closely follow his postures.
