Uthman bin Affan was the third Caliph of Islam and one of the closest companions of Prophet Muhammad (peace be upon him). He was born into the wealthy and influential Umayyad family of the Quraysh tribe in Mecca. Known for his modesty, generosity, and strong faith, Uthman embraced Islam in its early days, enduring persecution alongside other Muslims. He was well-regarded for his contributions to the Islamic community, including financing military expeditions and supporting the needy.
