The rules of evidence in Sharia courts traditionally prioritize oral testimony, and witnesses must be Muslim. Male Muslim witnesses are deemed more reliable than female Muslim witnesses, and non-Muslim witnesses considered unreliable and receive no priority in a Sharia court. In civil cases in some countries, a Muslim woman witness is considered half the worth and reliability than a Muslim man witness. In criminal cases, women witnesses are unacceptable in stricter, traditional interpretations of Sharia, such as those found in Hanbali jurisprudence, which forms the basis of law in Saudi Arabia.
