If You Find Identifiable Money on Shabbat, Does the Mitzvah of Returning Lost Property Still Apply?

This source-based Torah study examines the question: What should a person do when finding money with identifying signs on Shabbat, when the mitzvah of returning lost property meets Shabbat restrictions? A lost item found on Shabbat creates a meeting point between the duty to return property and the practical limits of Shabbat. It traces the issue through the parasha and the classical discussion without turning the material into an individualized ruling. The canonical review status is preserved for any practical, halakhic, ethical or theological claims.
