The Council of Islamic Ideology (CII) released a draft of the bill on Thursday, their response to progressive legislation giving women greater rights and protection in the province of Punjab.
Local media quoted the draft as saying: "A husband should be allowed to lightly beat his wife if she defies his commands and refuses to dress up as per his desires; turns down demand of intercourse without any religious excuse or does not take bath after intercourse or menstrual periods."
The country's biggest and most influential newspaper, the English-language daily Dawn, published a satirical article with a list of things people could beat other than their wives -- including eggs, the bottom of ketchup bottles, and the Michael Jackson hit Beat It.
The article was a rare example of the media mocking those claiming to speak in the name of religion in conservative Muslim Pakistan.

The draft was also slammed by the Human Rights Commission of Pakistan (HRCP), which condemned its recommendations as "ridiculous" and called for the council of "zealots" to be disbanded.
Online in Pakistan, the bill was met with derision.
"This body should be dissolved, preferably in acid," wrote one Twitter user, as others expressed bafflement and anger.
Women in conservative Pakistan have fought for their rights for decades, in a country where so-called honour killings and acid attacks remain commonplace.
But the Punjab Protection of Women Against Violence Bill redefines "violence" to include "any offence committed against a woman" including things like domestic or emotional abuse, stalking or cybercrimes.
It also allows courts to order a GPS tracker installed to monitor a defendant's movements.
The CII, formed in 1962 to advise parliament on the compatibility of laws with Sharia, has previously spoken out against the bill.
