Interestingly, it is most easily justified by the Koran. Taking advantage of infidel harlots is part of seizing "captives" of the faith. Mohammed dragged quite a few home to his harem himself.

Muslim males with money and power can do anything they please with full approval of Allah. As clever Aisha the child-bride said when Mohammed got permission from On High to take yet another wife, "How Allah hurries to please you."
