The Hady is a sacrificial animal (a sheep, goat, or a shared portion of a cow or camel) owed by pilgrims who combine Hajj with Umrah in one journey — those performing Tamattu' or Qiran — as an act of gratitude, not as expiation for a sin. The Quran states: "And complete the Hajj and Umrah for Allah. But if you are prevented, then [offer] what can be obtained with ease of sacrificial animals... And whoever cannot find [an animal] should fast three days during Hajj and seven when you return" (2:196). Pilgrims performing Ifrad (Hajj alone) do not owe this sacrifice, though they may offer one voluntarily.
The Hady is slaughtered from the 10th of Dhul-Hijjah (Eid al-Adha) through the end of the days of Tashreeq (the 13th), typically in Mina. Today most pilgrims arrange payment in advance through licensed banks or Hajj authorities, who handle the slaughter and distribution — meat is given to the poor, both locally and, increasingly, shipped to needy communities worldwide, fulfilling both the ritual and its charitable purpose.
