Queen Zubaydah was the wife of Caliph Harun Ar-Rasheed in the 9th century. She was highly educated and spiritual and was considered one of the scholars of her times. However, her lasting legacy is due to her philanthropy.

Queen Zubaydah was known to contribute greatly to public works, especially to accommodate travelers and pilgrims to Makkah. She built guest houses, lodges, roads, and wells on the routes to Makkah. She is also well known for the Zubaydah Canal. After being informed of a water shortage crisis, Queen Zubaydah had the canal built to channel water from the surrounding mountains into Makkah. The construction included other features such as tanks, reservoirs for rainwater retention and storage, and covers to prevent pollution from sandstorms.
