Al-Shafi'i Mosque is one of the oldest mosques in Jeddah, with foundations dating to the earliest centuries of Islam. While much of the current structure reflects 16th-century Ottoman style, its historic mihrab (prayer niche) is believed to be nearly 1,400 years old. The mosque is named after Imam Al-Shafi'i, a foundational scholar of Sunni Islamic jurisprudence. The building has been carefully restored, revealing intricate carvings and vibrant colour details. Non-Muslim visitors are welcome to enter outside of the five daily prayer times. Appropriate attire is required, and shoes must be removed before stepping onto the carpeted prayer areas.
