On the tenth, by daybreak, the holy monument, or _al Masher al harám_, is visited, after which the pilgrims hasten back, on the rising of the sun, to the Valley of Mina, where, on the 10th and the two following days, the stoning of the Devil takes place, every pilgrim casting a certain number of stones at three pillars. This rite is as old as Abraham, who, being interrupted by Satan when he was about to sacrifice his son Ishmael, was commanded by God to put the tempter to flight by throwing stones at him. Next, still on the same day, the tenth of Zú-’l-hijjah, and in the same place, the Valley of Mina, the pilgrims slay their victims, and when the sacrifice is over they shave their heads and trim their nails, and then return to Mecca in order to take their leave of the Ka’bah. All these ceremonies will be described in detail in the forthcoming narrative. Meanwhile, by way of further introduction, a few words must be said as to the animals sacrificed. The victims should be camels, kine, sheep, or goats. The camels and kine should be females and the sheep and goats males. In age the camels should be five years and not less; the cows and goats in their second year; and the sheep not younger than six months. All should be without blemish, neither blind nor lame: their ears should not have been cut, nor their horns have been broken. The males should be complete, and all be well fed. They were woefully lean, however, in the year 1319 of the Flight. The camels are sacrificed while standing, the fore and hind legs being tied together. A single blow is delivered where the head joins the neck, the name of God being uttered the while. The victim must face the Kiblah, and the butcher or the pilgrim, as the case may be, stands on the right of the animal he is going to slay. If the pilgrim be too tender-hearted to deal the blow, he should catch hold of the butcher’s wrist, so as to take part in the act of sacrifice. All the other victims--namely, the kine, the sheep, and the goats--are made to lie on their sides facing Mecca, all four legs being securely fastened, then their throats are cut with a sharp knife, without, however, severing the head from the body.
