Abraham, known as Ibrahim in Arabic, is very important in Islam, both in his own right as a prophet and as the father of Ishmael and Isaac. Ishmael, his firstborn son, is considered the father of some of the Arabs—specifically Father of the Arabised Arabs, peoples who became Arab—and Isaac is considered the Father of the Hebrews. Abraham is mentioned in many passages in 25 of the 114 suras (chapters) of the Qur'an, more than any other individual with the exception of Moses, according to the Encyclopedia of Islam.[26]
Abraham, commonly termed Khalil Ullah, "Friend of God" by Muslims, is revered as one of the Prophets in Islam, and the person who gave Muslims their name of Muslims ("those who submit to God"). He is considered a Hanif, that is, a discoverer of monotheism.[27]
According to tradition, Abraham's footprint is displayed outside the Kaaba, which is on a stone, protected and guarded by Saudi Arabian Mutawa (Religious Police). The annual Hajj, the fifth pillar of Islam, follows Abraham's, Hagar's, and Ishmael's journey to the sacred place of the Kaaba. Islamic tradition narrates that Abraham's subsequent visits to the Northern Arabian region, after leaving Ishmael and Hagar (in the area that would later become the Islamic holy city of Mecca), were not only to visit Ishmael but also to construct the first house of worship for God, the Kaaba—as per God's command.[28]
The ceremony of Eid ul-Adha, most important festival in Islam, focuses on Abraham's willingness to sacrifice his promised son Ishmael on God's command, as a test of Abraham's faith. God spared his son's life and substituted a fit sheep from heavens for his son. On Eid ul-Adha, Muslims sacrifice a domestic animal—a sheep, goat—as a symbol of Abraham's sacrifice, and divide the meat among the the family members, friends, relatives, and most importantly, the poor.
There are views stating that Qur’an does not specify whether it was Ishmael or Isaac whom Abraham was ordered to sacrifice. Muslims believe that it was Ishmael based on certain references from the Quran and several hadiths.[29][30][31][32]
