Under Islamic law, you can only prove rape if rapists agree that they rape or you have four male witnesses. But unfortunately men do not say that they rape and they do not rape in front of witnesses. Without witnesses a rape is considered to be adultery.
The Qur’an says,
Qur’an (2:282) – Establishes that a woman’s testimony is worth only half that of a man’s in court (there is no “he said/she said” gridlock in Islam).
Qur’an (24:4) – “And those who accuse free women then do not bring four witnesses (to adultery), flog them…” Strictly speaking, this verse addresses adultery (revealed at the very time that Muhammad’s favorite wife was being accused of adultery on the basis of only three witnesses coincidentally enough). However it is a part of the theological underpinning of the Sharia rule on rape, since if there are not four male witnesses, the rape “did not occur”.
Qur’an (24:13) – “Why did they not bring four witnesses of it? But as they have not brought witnesses they are liars before Allah.”
Qur’an (2:223) – “Your wives are as a tilth unto you; so approach your tilth when or how ye will…” There is no such thing as rape in marriage, as a man is permitted unrestricted sexual access to his wives.
And the Hadith says,
Bukhari (5:59:462) – The background for the Qur’anic requirement of four witnesses to adultery. Muhammad’s favorite wife, Aisha, was accused of cheating [on her polygamous husband]. Three witnesses corroborated the event, but Muhammad apparently did not want to believe it, and so established the arbitrary rule that four witnesses are required.
Saudi Arabia is doing exactly what Muhammad wanted to do. We are in the 21st century but we still are following 7th century’s laws! The woman could not find four witnesses, so she was seen as adulterous. She is now punished for adultery.
