Goats look out of a bus window, while being transported to a near by livestock market, to be displayed for sale in preparation for the upcoming Muslim holiday of Eid al-Adha, or "Feast of Sacrifice", on the outskirts of Islamabad, Pakistan, Thursday, Oct. 2, 2014. Muslims around the world will mark Eid al-Adha, as the biggest holiday of the Islamic calendar. It commemorates the willingness of the prophet Ibrahim _ or Abraham, as he is known in the Bible _ to sacrifice his son in accordance with God's will, though in the end God provides him a sheep to sacrifice instead.
