Ofcom, the broadcasting regulator, ordered Manchester-based DM Digital to pay an £85,000 fine for a programme which told Muslims it was their duty to kill anyone who insulted the Prophet Mohammed.
The company was also fined a further £20,000 for other breaches of the broadcasting rules.
Earlier this year The Telegraph revealed how a number of British-based Islamic stations, including DM Digital, were inciting violence and murder on the airwaves.
The new fines announced by Ofcom related to the programme Rehmatul Lil Alameen, or Mercy Unto the Worlds, broadcast in October 2011, and another entitled POAF Conference, broadcast in November and December 2011.
Rehmatul Lil Alameen featured a live lecture by Abdul Qadir Jilani, an Islamic scholar, which included material that Ofcom considered was “likely to encourage or incite the commission of crime or to lead to disorder”.
Mr Jilani, who is based in Walthamstow, east London, said in the offending programme: “The matter of insulting the prophet does not fall in the category of terrorism.
“Those who cannot kill such men have no faith.
“It is your duty, the duty of those who recite the holy verse, to kill those who insult Prophet Mohammed.
“Under the guidance from Islamic texts it is evident that if a Muslim apostatises, then it is not right to wait for the authorised courts; anyone may kill him.
“An apostate deserves to be killed and any man may kill him.”
A spokesman for the regulator said: “Ofcom decided that this code breach was particularly serious … and, taking account of all the circumstances, decided therefore that a financial penalty of £85,000 should be imposed on the licensee DM Digital.”
The other programme featured comments by Dr Liaqat Malik, DM Digital’s chief executive, which breached Ofcom’s views on political statements and impartiality, leading to a £20,000 penalty.
Earlier this year Dr Malik told The Telegraph he was dissatisfied with Ofcom’s ruling.
“There are cultural differences and I think Ofcom doesn’t understand that. Some of the Ofcom committee members should be picked from the Muslim community,” he said.
