Almost every muslim had heard the Quranic story in Surah Al-Fil which tells us about the story of the Yemeni king who brought a huge army equipped with elephants to destroy the Kaaba in Makkah.
At that time Elephants were considered the most sophisticated weapon for a well equipped army, so the Abraha the king of Yemen was sure that he will be successful in destroying the Kaabah.
When his army reached near the city of Makkah some birds which are considered to be Ababeel. The flock of birds came from the side of the ocean carrying gravels, two in their claws and one in their beak, througing them on the elephants.
This fierce attack from the small birds forced the big elephants to run away, Abraha with all its mighty army was unable to demolish the Kaaba. In this story there is a message for Allah that if you are on the side of the Allah then He almighty will protect you even from the most sophisticated and well equipped armies and kings.
