Eid-al-Adha or Eid-ul-Zuha honors the willingness of Abraham to sacrifice his son as an act of submission to God's command. This is celebration of his faith in Allah which didn't weaken even after provocation from Satan on the way. He firmly believed that Allah would do no harm to his son and that happened when his son replaced with a sheep. Happy Eid.
millions gather in the holy city,
follow the procedures of the prophet,
hit stones to the greed with alacrity,
displaying faith in Allah like the prophet,
sacrificing bad in you and not just an animal,
feeding hungry and caring the needy,
detach from loved possession and not just an animal,
come out from Satan's pity.
