It's speaking after the Home Secretary Theresa May (below) launched the independent inquiry after claims some women had been discriminated againsy in Sharia courts, with reports some were legitimising forced marriages or offering unfair divorces.
Christian Concern has said that "everybody knows sharia law is discriminatory", however a Muslim interfaith worker who used to be employed by Blackburn Cathedral has said that Sharia law is about looking after your neighbour and not harming anyone.
It's been reported that thousands of Muslims settle civil matters in Sharia courts each year in the UK. They do not have legal status in the UK.
The review into their practices, chaired by Islamic expert Mona Siddiqui, will present its findings in 2017. It was launched as part of the government's counter-extremism strategy.
Tim Dieppe, the Director of Islamic Affairs at Christian Concern, told Premier: "Everybody knows sharia law is discriminatory.
"It's absolutely clear in the Quran that polygamy is allowed, a woman's testimony is worth half that of a man, a man can inherit twice as much as women...
"We know that it's incompatible with the law in England and Wales, so why do we need a review to establish that?
"The European Court of Human Rights ruled back in 2003 that Sharia law is incompatible with the fundamental principles of democracy."
Anjum Anwar, formerly of Blackburn Cathedral, told Premier's News Hour: "People seem to assume that Sharia is all about chopping hands and heads off.
"Three million are actually living in United Kingdom according to the Sharia; that is, that you look after your neighbour, that you cannot go to bed knowing that your neighbour has not had enough food to eat, and that you cannot harm anyone - these are all according to the Sharia."
Home Secretary Theresa May said: "Many British people of different faiths follow religious codes and practices, and benefit a great deal from the guidance they offer.
"A number of women have reportedly been victims of what appear to be discriminatory decisions taken by Sharia councils, and that is a significant concern.
"There is only one rule of law in our country, which provides rights and security for every citizen.
"Professor Siddiqui, supported by a panel with a strong balance of academic, religious and legal expertise, will help us better understand whether and the extent to which Sharia law is being misused or exploited and make recommendations to the government on how to address this."
