Sumud in this sense has meant "staying put despite continuous assault." It is not merely about passive endurance, but "an act of unyielding resistance and defiance." Palestinian refugees, both those living within and outside of the occupied territories, often describe their ability to both resist and endure camp life as sumud. The holding out of Palestinian refugees against the assaults on Tel al-Zaatar and Sabra and Shatila in Lebanon are cited as prime examples of sumud.
