Government, semi-government and autonomous institution buildings have been illuminated marking the festival.
Bangladesh Television, Bangladesh Betar and private television channels are airing special programmes on the occasion.
Special meals will also be served at hospitals, orphanages, prisons and child care centres.
After offering Eid prayers, Muslims will sacrifice animals seeking the blessings of the Almighty Allah.
The practice of Qurbani commemorates the supreme devotion of Hazrat Ibrahim (AS), who was prepared to sacrifice his beloved son Hazrat Ismail (AS) in obedience to Allah’s command.
The Almighty Allah later replaced Ismail (AS) with a sacrificial animal, symbolising the spirit of faith and sacrifice.
Eid-ul-Azha is also deeply linked with the holy Hajj. Eid is being observed in Saudi Arabia today as Hajj pilgrims have already performed major rituals at Arafat, Muzdalifah and Mina.
