The story of Qurbani is about Prophet Ibrahim’s devotion to Allah. He dreamed Allah asked him to sacrifice his son, Ismail. He prepared to obey, and Ismail also accepted. As he was about to sacrifice him, Allah replaced Ismail with a ram. This showed their strong faith, and Muslims honor this act during Eid al-Adha. https://www.dawateislami.net/bookslibrary/ur/ibrahim-ka-qurbani-karnay-ka-waqia
