من كان أول شخص اعتنق الإسلام؟

That's correct! Khadija bint Khuwayled (often spelled Khadijah) is widely recognized in Islamic history as the very first person to accept Islam, standing by the Prophet Muhammad from the very beginning of his mission. Ali ibn Abi Talib, who was raised in the Prophet's household, was indeed the first youth and the first male to accept Islam.

These early figures played foundational roles in supporting the Prophet during the earliest, most challenging days of the faith in Mecca.
