An influential Muslim scholar has issued a global ruling against terrorism and suicide bombing.Dr Tahir ul-Qadri, from Pakistan, says his 600-page judgement, known as a fatwa, completely dismantles al-Qaeda's violent ideology. The scholar describes al-Qaeda as an "old evil with a new name" that has not been sufficiently challenged. The scholar's movement is growing in the UK and has attracted the interest of policymakers and security chiefs.
