(Sydney Morning Herald) — Just months after telling its members to serve their husbands better than prostitutes, prompting widespread criticism, the Obedient Wives Club of Malaysia has stirred further controversy by publishing a guide to Islamic sex.

The 115-page pocket-sized book, which will outrage many Muslims and non-Muslims, says a Muslim man can have sex with all of his wives at the same time.

Under strict Islamic tradition a man can have up to four wives if he can provide for them all.

In its foreword the book says studies showed women only gave their husbands 10 per cent of what men desired of their wives’ bodies. It contains explicit sex details, including fondling of a breast, and one chapter deals with ”how sex becomes worship”.

The book is circulating in Malaysia at a time when radical Islam is expanding across Asia through a movement called Hizbut Tahrir, which is attracting many middle-class Muslims, including businessmen, lawyers and mothers.

Hizbut Tahrir wants to unite all Muslim countries in a globe-spanning bloc ruled by strict sharia law. It is operating openly in Australia.
