HaJI at-Tamattu - [7]H

 Haji  at-Tamattu'

It is obligatory for a pilgrim who performs hajj tamattu' (performing 'umrah before assuming ihram for hajj) to slaughter a animal (hady) after 5 releasing himself from ihram, conforming to the words of Allah Almighty Who says,

Then whoever performs 'umrah [during the Hajj months] followed by Hajj [offers] what can be obtained with ease of sacrificial animals. And whoever cannot find [or afford such an animal] - then a fast of three days during Hajj and of seven when you have returned [home]. Those are ten complete [days]. This is for those whose family is not in the area of al-Masjid al-Haram. [Al-Baqarah, 196]

It is permissible for a pilgrim to slaughter in Mecca after releasing himself from ihram for 'umrah, in Mina on the day of 'Eid, on the days of tashriq (the 3 days following 'Eid), or in Mecca after returning from Mina. It is permissible for a pilgrim to eat from the meat of the sacrificed animal.
