October 26 marks the Islamic Eid al-Adha festival, which is also known as the "Feast of Sacrifice" in English. Over the course of this holiday period, Muslims across the globe have been slaughtering their best halal animals as a symbolic homage to the willingness of the prophet Ibrahim (Abraham) to sacrifice his first son as an act of supplication to God. (Like the Christian telling of this tale, God thankfully intervened at the last moment and provided Ibrahim with a ram to kill instead). According to some estimates, as many as 100 million animals will be slaughtered across the Muslim world during Eid. As is traditional, a significant portion of the meat from these beasts will be distributed to the poor and needy. (13 PHOTOS)
