This surah was revealed in Makkah, and talks about how Allah protected Al Ka'bah from an invading army known as the people of the elephant. This army was strong and mighty, but Allah, the Almighty Lord of Al Ka'bah, protected His house using the least expected weapons. In obedience of Allah's command and against the army's order, the elephants refused to march toward Al Ka'bah. And although very insignificant compared to the elephants, birds carrying baked clay were sent to stone the soldiers to death while causing no harm to the elephants and the people of Makkah.
