Just about every major faith group has condemned the plan to redefine marriage at this point:

"...the Muslim Council of Britain said case for the government’s proposals was “strikingly weak”.

Farooq Murad, Secretary General of the MCB, said: “Whilst we remain opposed to all forms of discrimination, including homophobia, redefining the meaning of marriage is in our opinion unnecessary and unhelpful.

“With the advent of civil partnerships, both homosexual and heterosexual couples now have equal rights in the eyes of the law.

“Therefore, in our view the case to change the definition of marriage, as accepted throughout time and across cultures, is strikingly weak.

In common with other Abrahamic faiths, marriage in Islam is defined as “a union between a man and a woman”, he said. “So while the state has accommodated for gay couples, such unions will not be blessed as marriage by the Islamic institutions.” -- UK Telegraph
