In Islamic tradition, it honours the willingness of Abraham to sacrifice his son as an act of obedience to God's command.

Depending on the narrative, either Ishmael or Isaac are referred to with the honorific title "Sacrifice of God".

[17][18] Arthur Jeffery contests this etymology, and believes the term to have been borrowed into Arabic from Syriac, or less likely Targumic Aramaic.

The first word comes from the triliteral root ضحى (ḍaḥḥā) with the associated meanings "immolate; offer up; sacrifice; victimize".

[18] Arthur Jeffery recognizes the same Semitic root, but believes the sense of the term to have entered Arabic through Aramaic.

[19] Eid al-Adha is pronounced Eid al-Azha and Eidul Azha, primarily in Iran and influenced by the Persian language like the Indian subcontinent; /ˌiːd əl ˈɑːdə, - ˈɑːdhɑː/ EED əl AH-də, -⁠ AHD-hah; Arabic: عيد الأضحى, romanized: ʿĪd al-ʾAḍḥā, IPA: [ʕiːd al ˈʔadˤħaː].

One of the main trials of Abraham's life was to receive and obey the command of God to slaughter his beloved son Ishmael.

Many Muslims celebrate Eid al-Adha to commemorate both the devotion of Abraham and the survival of his son Ishmael.

[35] At the conclusion of the prayers and sermon, Muslims embrace and exchange gifts and greetings with one another, such as the phrase Eid Mubarak.

The tradition for Eid al-Adha involves slaughtering an animal and sharing the meat in three equal parts – for family, for relatives and friends, and for poor people.

While some scholars, such as Al-Kasani, categorise the sacrifice as obligatory (wāǧib), others regard it only as an "established custom" (sunna mu'akkada).

[45]Muslims are expected to dress in their finest clothing to perform Eid prayer in a large congregation in an open waqf ("stopping") field called Eidgah or mosque.
