Muslims are marking Eid al-Adha, commemorating 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 provided him with a sheep to sacrifice instead. The name of the religious day is translated as "festival of the sacrifice". On the first day of Eid al-Adha, Muslims slaughter sheep, cattle and other livestock, and give part of the meat to the poor.
In this picture gallery, IBTimes UK looks at how Muslims around the world celebrated Eid al-Adha.
