Islamic scholar promotes adult breastfeeding:

...Izzat Atiyaa had issued a fatwa, or religious ruling, offering his bold suggestion as a way around the prohibition in Islamic religious law against a woman working in private premises with a man who was not her close relative. Breastfeeding, he argued, would create a familial relationship under Islamic law. Dr Atiyaa explained to the Egyptian newspaper al-Watani al-Yawm that: "A man and a woman who are alone together are not (necessarily) having sex but this possibility exists and breastfeeding provides a solution to this problem (by) transforming the bestial relationship between two people into a religious relationship based on (religious) duties."
