Eid al-Adha, or the 'Feast of Sacrifice', is a Muslim festival celebrated across the globe, marking the willingness of Abraham to offer up his son to Allah. While many Muslims mark the occasion by visiting Mecca in a pilgrimage known as 'Haaj', those unable to make the trip mark the feast in their homelands. Here are some photos showing the many ways Muslims mark the occasion around the world.
