A confession, an oath, or the oral testimony of Muslim witnesses are the main evidence admissible in traditional sharia courts for hudud crimes, i.e., the religious crimes of adultery, fornication, rape, accusing someone of illicit sex but failing to prove it, apostasy, drinking intoxicants and theft. According to classical jurisprudence, testimony must be from at least two free Muslim male witnesses, or one Muslim male and two Muslim females, who are not related parties and who are of sound mind and reliable character. Testimony to establish the crime of adultery, fornication or rape must be from four Muslim male witnesses, with some fiqhs allowing substitution of up to three male with six female witnesses; however, at least one must be a Muslim male. Forensic evidence ("i.e.", fingerprints, ballistics, blood samples, DNA etc.) and other circumstantial evidence may likewise rejected in hudud cases in favor of eyewitnesses in some modern interpretations. In the case of regulations that were part of local Malaysian legislation that did not go into effect, this could cause severe difficulties for women plaintiffs in rape cases. In Pakistan, DNA evidence is rejected in paternity cases on the basis of legislation that favors the presumption of children's legitimacy, while in sexual assault cases DNA evidence is regarded as equivalent to expert opinion and evaluated on a case-by-case basis.
