“Neither their meat nor blood reacher Allah. Rather, it is your piety that reaches Him.” (Surah Hajj ,22/37) The main purpose of all worship is to be close to Allah and to get His approval. Therefore sacrifice is a declaration of respect and submission to Allah by the pious servants who are aware of their responsibilities towards Him. Muslims remember Abel and Cain, the Prophet Adam's sons and also Prophet Ibrahim and his son Ishmael, who were put to a test of sincerity with their vows for Allah.
