As i am muslim the islamic law about rape is completely forbidden in Islamic law, and is a crime punishable by death.
In Islam, capital punishment is reserved for the most extreme crimes which harm individual victims or destabilize society. Rape falls into both of these categories.
Islam takes very seriously the honor and protection of women. The Quran repeatedly reminds men to treat women with kindness and fairness. Rape is a horrible crime which causes a women humiliation and physical harm(forbidden).
Don't talk about the Islamic law. In Islamic nations, the women are treated as even less worthwhile than camels or goats. And if a rape happens, usually the victim is punished instead of the perpetrator.
