Today, Muslims around the world will be celebrating the holy festival of Eid al-Adha.
The festival falls on the 12th day of Dhu al-Hijjah – the 10th and final month of the Muslim lunar calendar.
It commemorates the story of the prophet Ibrahim, who was prepared to sacrifice his own son, Ismael, for God.
But the command was a test, and before Ibrahim could carry out the sacrifice, God stopped him and spared Ismael.
Muslims honour this tale, and its message of devotion, by praying together, feasting and exchanging gifts.
In some countries it is traditional to celebrate Eid al-Adha by sacrificing an animal, and dividing the meat equally between family at home, relatives and the less fortunate.
What does Eid Mubarak mean?
Muslims will wish each other “Eid Mubarak” during the festivals of Eid al-Adha and Eid al-Fitr.
This literally translates as “blessed festival” or “blessed celebration”, but its meaning is essentially “happy Eid”.
If someone wishes you an Eid Mubarak, you can reply by saying “Khair Mubarak”, which wishes goodwill on the person who greeted you.
Eid al-Adha lasts for four days, and will end on Monday 3 August.
Muslims will begin their celebrations this morning with a prayer known as Eid Salat, or the Eid congregational prayer.
Communities come together to perform this prayer in open congregations.
After prayers have concluded, Muslims embrace, wish each other Eid Mubarak, give gifts, and visit one another at home.
This year Eid celebrations will be limited by the lockdown coronavirus restrictions.
