The sacrifice (hady) is farz for hacilar performing Hac al-Tamattu and Hac al-Qiran, based on Kur'an-i Kerimic verse: 'And whoever enjoys Umre followed by Hac must offer what is easily available of sacrificial animal. But whoever cannot find (one) — then a fast of three days during Hac and seven when you return home. That is ten complete days' (2:196). This verse establishes both the obligation of sacrifice and the alternative of fasting for those unable to afford it.
Sheikh Ibn Baz explained that the sacrifice is a gratitude offering (shukr) for the blessing of combining Umre and Hac in one journey, saving the haci the cost and effort of separate trips. The minimum acceptable sacrifice is one sheep or goat that meets the age requirements (six months for sheep, one year for goats). Alternatively, a haci may share in a one-seventh portion of a camel or cow (seven hacilar sharing one camel or cow). The animal must be free of defects that would disqualify it.
Sheikh Ibn Uthaymeen clarified that hacilar performing Hac al-Ifrad (Hac alone without Umre) are not required to offer a sacrifice, as they did not combine two acts of worship. He also noted that residents of Mekke who perform Tamattu are not required to offer a sacrifice alimlerin cogunluguna gore, based on the continuation of the verse: 'This is for those whose family is not present at al-Mescid-i Haram.' The sacrifice obligation applies to non-Mekke residents who perform Tamattu or Qiran.
