Dawood (David) was chosen by Allah to be a prophet. He was noble, brave, honest, just, kind, and humble throughout his lifetime. David was very stoic and courageous when he fought Goliath. When Goliath laughed at him, David stood his ground and swung his slingshot as fast as he could, and it promptly hit Goliath right in the center of his forehead.
David was also brave because he was only half of the size of Goliath, who was an undefeatable giant. Everyone can learn a lesson from David, who knew the power of his strength, even if he was not as fierce or aggressive as his competitor. David still knew that he was extremely accurate at hitting a target with his slingshot. David was also not afraid to accept the challenge and fight Goliath.
