An Ayatollah is a high-ranking title given to Shia Islamic scholars who are recognized for their expertise in Islamic law and theology. The term means "sign of God" in Arabic, and Ayatollahs play a significant role in guiding the beliefs and practices of Shia Muslims. They often lead religious communities, provide interpretations of the Quran, and offer guidance on moral and ethical issues. In countries like Iran, Ayatollahs hold considerable political influence as well. The most prominent Ayatollah, such as Ayatollah Khomeini, can lead not only in spiritual matters but also in governance, shaping laws and policies based on Islamic principles. Their authority is derived from their knowledge and the respect they command within the community.
