Eid-ul-Adha ('festival of Sacrifice'), also known as the Greater Eid, is the second most important festival in the Muslim calendar.The festival remembers the prophet Ibrahim's willingness to sacrifice his son when God ordered him to.
The story of Ibrahim's sacrifice
Eid-ul-Adha celebrates the occasion when Allah appeared to Ibrahim in a dream and asked him to sacrifice his son Isma'il as an act of obedience to God.
The devil tempted Ibrahim by saying he should disobey Allah and spare his son. As Ibrahim was about to kill his son, Allah stopped him and gave him a lamb to sacrifice instead.
Eid usually starts with Muslims going to the Mosque for prayers, dressed in their best clothes, and thanking Allah for all the blessings they have received.
It is also a time when they visit family and friends as well as offering presents.
