Senegal. Saint-Louis. The Muslim festival of Eid-al-Adha (commonly translated as the Feast of Sacrifice) or Eid el-Kebir is the most important Muslim festival. It is called Tabaski in West African countries. The Eid prayer is performed on the morning of Eid al-Adha, after which udhiyah, or the ritual sacrifice of sheep, may be performed. In Islamic tradition, it honours the willingness of Abraham to sacrifice his son as an act of obedience to God's command.
