Place and time of slaughtering the sacrificial animal to be offered

The sacrificial animal to be offered, be it obligatory or voluntary, should be slaughtered only in the Sanctuary, except for two kinds:

First: what is due because of committing one of The Hajj’s forbidden action save killing the game: it is permissible to slaughter it in the Sanctuary or in the very place where the forbidden act was committed.

Second: what is due because of prevention, which should be slaughtered where one was prevented.

The giver of a sacrificial animal has the right to slaughter it anywhere within the limits of the Sanctuary, in view of the statement of the Messenger of Allaah, sallallaahu ‘alayhi wa sallam: "The whole area of Mina is fitting for a slaughtering place, and all the streets of Makkah are approved as entrances to it and as a slaughtering place." [Abu Daawood]

The time of slaughtering starts from the day of  Nahr once an interval of time enough for offering ‘Eed prayer elapses after the sun rises as much as a spear’s length, and it extends to the sunset of the last of the days of Tashreeq, according to the right opinion, i.e. the 13^th of Thul-Hijjah, in view of the statement of the Messenger of Allaah, sallallaahu ‘alayhi wa sallam: "All days of Tashreeq are fitting for slaughtering." [Ahmad]

It is favorable for one to slaughter his sacrificial animal by himself, or may delegate someone to do it on his behalf. The Prophet, sallallaahu ‘alayhi wa sallam, slaughtered with his hand sixty-three camels and then gave Ali, May Allaah Be Pleased with him, (permission) to slaughter the remaining thirty-seven.

One has the right to eat from the voluntary sacrificial animal or that which is offered for Tamattu` or Qiraan, and give out as a present or charity thereof, unlike the other kinds of sacrificial animals; and Allaah Knows best.
