Last weekend's celebration of Eid al Adha is one of the two most significant days on the Islamic calendar.
Translating to 'The Festival of Sacrifice', it marks the willingness of Ibrahim (Abraham) to sacrifice his son to god. The angel Jibra'il (Gabriel) intervened to inform him that the sacrifice was no longer necessary, the parable goes.
It's Islamic tradition to sacrifice an animal - such as a goat, cow or camel - and divide the meat into three parts.
The family retains a third, another third is given to relatives and friends, while the remaining third is given to the poor. The donation of meat can also be made metaphorically, with gifts to charities.
From Beirut to Sydney, Tokyo to Gaza, more than one billion Muslims around the world marked the festival this weekend with friends and family.
