Sadly, compliance with the request has been swift and complete, and Cambridge has gone to great lengths to kowtow to bin Mafouz. It seems that Mr. bin Mafouz makes a bit of a habit of bringing suit in Britain against authors and publishers, due to Britain's archaic libel laws which place the burden of proof on the accused. Bin Mafouz has done this no less than seven times, as described on his own web site.
Here's the text of Cambridge's apology:
In 2006 Cambridge University Press published Alms for Jihad written by J. Millard Burr and Robert O. Collins which made certain defamatory allegations about Sheikh Khalid Bin Mahfouz and his family in connection with the funding of terrorism.Note how Cambridge has recognized and accepted the accusations. Nowhere in the apology do they state that they've determined the accusations to be true.
Whilst the allegations were originally published in good faith, Cambridge University Press now recognises that the information upon which they were based was wrong. Cambridge University Press accepts that there is no truth whatsoever in these serious allegations.
Cambridge University Press accepts that the entire Bin Mahfouz family categorically and unreservedly condemns terrorism in all its manifestations, and that at no time has any member of the family contributed to any terrorist organisation, nor has the family ever had reason to believe that funds it has given over the years to a wide variety of charities, including the Muwafaq Foundation, have been used other than for the charitable purposes intended.
Cambridge University Press has given its sincere apologies to Sheikh Khalid and his family for the distress and embarrassment caused, and has undertaken not to publish those allegations or any similar allegations in the future.
To emphasise their regret, Cambridge University Press has agreed to pay Sheikh Khalid substantial damages and to make a contribution to his legal costs, both of which Sheikh Khalid is donating to the charity UNICEF.
