These pictures are from the morning of Eid al-Adha in the Fes Medina .  Eid al-Adha is an important religious holiday for Muslims that commemorates Abraham’s willingness to sacrifice his son Ishmael in the name of G-d.  Muslims believe, that just before Abraham was about to sacrifice his son, G-d intervened and replaced him with a sheep.  This is why Muslims sacrifice a sheep on Eid al-Adha.
