Quran 24:13 requires corroborating testimonies from four male witnesses to prove the rape of a girl or woman:
"Why did they not bring four witnesses to prove it? When they have not brought the witnesses, such men, in the sight of Allah, (stand forth) themselves as liars!" - Quran 24:13
The reporting and prosecution of such attacks are rare in the Muslim world since if the female plaintiff is unable to produce four male witnesses, she will be charged with lying, as well as adultery, which is a capital offense under Sharia law.
