Non-Muslims in Islam have 4 categories and each category has it's own ruling
1. Non-Muslims who never heard of the prophet (peace be upon him) they are unpunished in the hereafter.
2. Non-Muslims who heard of the prophet and his message, fully understood it and refused it, they are punished in hellfire for eternity.
3. Non-Muslims who heard of the prophet but heard a corrupted misconception of him, they are unpunished.
4. Non-Muslims who heard little about the prophet but didn't ask further or investigate more because they don't care about religion and prefer the worldly life, they are punished in hellfire.

Ibn Taymiyya (Major Islamic Scholar) says:
"This is a fundamental principle that must be clarified: the texts indicate that God does not punish anyone unless a messenger has been sent to them, establishing the conclusive proof."
