Millions of Muslims around the world will celebrate the second holy festival of the year this month.
In June, Muslims marked Eid al-Fitr, after abstaining from food and drink from sunrise to sunset during the fasting period of Ramadan.
But Muslims are soon to commemorate another Islamic holiday known as the Feast of Sacrifice - Eid al-Adha.
The Hajj pilgrimage to Mecca in Saudi Arabia coincides with celebrations of Eid al-Adha, which sees Muslims who are physically and financially capable embark on the journey at least once in their lifetime.
Here's everything you need to know ahead of the festival; when Eid al-Adha is, why it's celebrated, and how.
What date is Eid al-Adha?
This year the holy festival will start on the evening of Sunday, August 11 and will come to a close four days later on Thursday, August 15. However this could alter depending on the sighting of the moon of Dhul Hijjah.
Eid al-Adha falls under the twelfth month of the Islamic calendar, the same as Hajj, so it's considered to be a particular sacred month of the year.
The festival dates change each year because the occasion is celebrated on the tenth day of that month, which of course changes each year.
What is the festival about?
The event honours Abraham’s willingness to sacrifice his son to obey God’s command.
Abraham was a prophet and messenger, and despite being willing to sacrifice his son, God instead provided a lamb for him to sacrifice.
How is it celebrated?
Similarly to Eid al-Fitr, the greeting Eid Mubarak is shared and gifts are exhanged.
Families and large groups will get together to mark the occasion to pray and enjoy a feast.
In commemoration of sacrifice, Muslims in some countries will slaughter their animals and divide the meat into three parts; typically a third is kept for the family, another is given to friends and relatives, and a final third is donated to the poor.
