Judaism
Regarded as an ancestral patriarch and head of one of the Twelve Tribes, rather than a prophet. Jewish tradition exalts Judah for his leadership and as the ancestor of the Davidic royal line.
Christianity
Judah is not classified as a prophet. He is viewed as a patriarch whose tribe was prophesied to hold the sceptre of kingship, culminating in the lineage of Jesus Christ (the "Lion of the tribe of Judah").
Islam
Viewed as the ancestor of the Israelites and one of the sons of Prophet Jacob. He is treated as a foundational figure in the lineage of the tribes, though not categorized as a prophet himself.
