Which is better for naming a newborn: Hamza or Jasir?

A name has an effect on the character of its bearer, and the Prophet commanded that names be improved. The name "Jasir" means courageous and daring, and "Hamza" comes from al-hamaza, which signifies strength and firmness, and it is one of the names of the lion. Hamza ibn Abd al-Muttalib, the uncle of the Prophet (peace and blessings be upon him), was one of the lions of Islam, known for his courage and daring. Naming with Hamza is better, as it encompasses the meaning of the name Jasir and adds to it the distinction of being the name of a great companion whose courage is exemplary.
