In this Surah, God's punishment which was inflicted on the people of the elephant is referred to and described very briefly because it was an event of recent occurrence, and everyone in Makkah and Arabia was fully aware of it. That's why the Arabs believed that the Ka'bah was protected in this invasion, not by any god or goddess, but by God Almighty Himself. Then God alone was invoked by the Quraysh chiefs for help, and for quite a few years the people of Quraysh, having been impressed by this event, had worshiped none but God.
