Quran 28:15 — History (Al-Qasas)

Once he entered the city unexpectedly, without being recognized by the people. He found two men fighting; one was (a Hebrew) from his people, and the other was (an Egyptian) from his enemies. The one from his people called on him for help against his enemy. Moses punched him, killing him. He said, "This is the work of the devil; he is a real enemy, and a profound misleader."

[28:14] When he reached maturity and strength, we endowed him with wisdom and knowledge. We thus reward the righteous.

[28:16] He said, "My Lord, I have wronged my soul. Please forgive me," and He forgave him. He is the Forgiver, Most Merciful.
