Qurbani is the sacrifice of an animal during the festival Eid ul Adha. The significance of this relates to the event that took place during the time of Prophet Ibrahim Alayhissalam. This is when he in a dream was commanded to sacrifice his son for Allah. After much deliberation, he finally set out to sacrifice his beloved son. We must remember Ibrahim waited many years to finally have a son. He was 86 years old when his son was born so one can imagine the love he had for his son. And to now sacrifice him.
