In Islamic jurisprudence, Ra'y is a mode of Ijtihad which technically means "considered opinion". It refers to the independent legal reasoning of a jurist based on their own analysis of the Quran and Sunnah, as well as other sources of Islamic law. Ra'y is based on personal reasoning and judgment, and is considered a valid form of Ijtihad as long as it follows established principles and methodology of Islamic jurisprudence. However, Ra'y is not always universally accepted, and is subject to debate and criticism by other scholars. Despite this, Ra'y has been an important tool in the development of Islamic jurisprudence, and has contributed to the richness and diversity of Islamic legal thought.
