Harun, or Haroon, was a prophet in the Qur'an. In the Bible he is known as Aaron.

Harun was the elder brother of Musa, who in the Bible is known as Moses. Along with his brother, he was a prophet who was tasked by God with saving the Israelites from the tyrannical Pharaoh. Harun was a gifted speaker, and would often speak for Musa who suffered from a speech-impediment. He was largely responsible with teaching the Israelites the way of worship as laid out in the Torah. He would die at Mount Hoor.
