Thousands of Muslims from across the world converged on the UK for a convention where they rejected extremism and violence of terror groups such as Isis. More than 30,000 members of the Ahmadiyya Islamic movement met ... in Hampshire for a three-day convention, the 50th time the annual event has taken place. On the final day, attendees were led by the global Caliph of the movement in a vow of peace and a pledge of allegiance to their home countries. The only thing the terrorists are achieving is to completely violate the teachings of the Holy Koran and of the Holy Prophet Muhammad," His Holiness Hazrat Mirza Masroor Ahmad told attendees. "Let it be clear that they are not practising Islam, rather it seems as though they have invented their own hate-filled and poisonous religion." The Ahmadiyya movement has 129 centres across the UK including the Baitul Futuh Mosque in south London, the biggest in Western Europe. The movement was founded in India in 1889 with a strong emphasis of peace over violence and tolerance over extremism. The president of the UK Ahmadiyya Muslim Community, Rafiq Hayat, said: "The 30,000-plus people from over 90 countries gathering at the convention come in the spirit of fraternity - and to give thanks for the security and freedom they have found in Britain. "Many have fled persecution in other countries and together, they will re-affirm their pledge to follow the true teachings of Islam - that are teachings of peace - and to counter all forms of extremism and intolerance.
