For example, while the Koran allows for a measure of female inheritance, tribal custom does not authorize it, which explains the popularity of tribal councils to resolve inheritance problems and cheat women out of their rights. Similarly, whereas the Koran requires four eyewitnesses as proof of adultery, mere suspicion of some unregulated, potentially sexual conduct by a woman warrants stoning under customary law.
比方说，尽管古兰经允许对女性的继承权进行考量，但部族惯例对此却并不认可，这也可以解释为什么靠欺骗妇女放弃继承权来解决继承问题在部族委员会如此盛行。同样，古兰经规定必须有四名目击证人才能证实通奸罪，但仅仅怀疑一名女性可能发生过违法性行为就足以按照习惯法的规则对其处以石刑。
