The instructions come in a religious diversity handbook given to Victorian police officers that also recommends special treatment for suspects of Aboriginal, Hindu and Buddhist background.
Police are told: "In incidents such as domestic violence, police need to have an understanding of the traditions, ways of life and habits of Muslims."
They are told it would be appreciated in cases of domestic violence if police consult the local Muslim religious leader who will work against "fragmenting the family unit".
Islamic Women's Welfare Council head Joumanah El Matrah called the guidelines appalling and dangerous.
The guide also advises officers not to hold interviews with Aboriginal suspects or set court hearings during Aboriginal ceremonies involving "initiation, birth, death, burials, mourning periods, women's meetings and cultural ceremonies in general".
They are told to interview Baha'i suspects only after sunset in the fasting month.
And they are cautioned that when a Sikh is reading the Sikh Holy Script -- a process that normally takes 50 hours -- "he should not be disturbed".
The 50,000 handbooks instruct police to take shoes off before entering Buddhist and Hindu houses and mosques, and remove hats before entering or searching churches.
Australasian Police Multicultural Advisory Bureau head Gerard Daniells, who created the 82-page full-colour handbook, said common sense would prevail over the guide in an emergency.
Mr Daniells said the next edition would include Maori spiritual beliefs and practices.
The NEXT bloody edition? A hallmark of a cohesive civil society is equal protection under the law. Taking off shoes before entering a mosque? Not interrupting a reading of the Sikh holy script?
