article: The influence of the movement has been in the spotlight again in Mr Gulen's home country, where a feud between his followers and other members of the political class has been blown into the open by a series of arrests. Ill-feeling is said to have grown since the Turkish government moved to close down a network of private schools run by Hizmet. Until then, the movement played a part in driving the electoral success of Prime Minister Recep Tayyip Erdogan's Islamist-rooted AK Party, which has been in power for three terms. But the movement's influence extends far beyond Turkey, funding schools, and think tanks and media outlets, from Kenya to Kazakhstan. It has attracted millions of followers and billions of dollars. Hizmet has no formal structure, no visible organisation and no official membership, yet it may have grown into the world's biggest Muslim network. Its name means "service" and it promotes work for the common good, with advocates saying they simply work together in a loosely affiliated alliance inspired by the message of Mr Gulen. The imam promotes a tolerant Islam which emphasises altruism, hard work and education. There are said to be millions of Hizmet followers in Turkey, where they are believed to hold influential positions in institutions from the police and secret services to the judiciary and the AK Party itself. Followers are said to donate between 5% and 20% of their income to groups affiliated with the movement. The movement's schools usually boast hi-tech facilities, and many students are on scholarships funded by Gulen-inspired businessmen. Although the schools are secular, teachers are expected to act as role models. Smoking, drinking and divorce are frowned upon. Fatma Disli first came across the movement at a school it founded to help students pass university admissions tests. "The people I met through Hizmet were really hard-working, virtuous people who were practising their religion, but at the same time had important jobs," she told BBC News. "I realised that it's possible to be religious and to have a career." Turkish businessmen are attracted by what they see as Mr Gulen's international outlook and pragmatic approach to issues like using credit. The mix of philanthropy and business appears to have been powerful, with Gulen-inspired schools supporting and smoothing the way for Turkish businessmen in emerging markets like Africa and Central Asia. However, critics believe the movement's aim is to gain power, to spread socially conservative Islamic attitudes on issues like marriage and alcohol around the globe, and to suppress any opposition. Opponents of the movement point to a video which surfaced in 1999, in which Mr Gulen seemed to tell his followers that they should deliberately attempt to infiltrate mainstream structures: "You must move within the arteries of the system, without anyone noticing your existence, until you reach all the power centres. "You must wait until such time as you have got all the state power, until you have brought to your side all the power of the constitutional institution in Turkey." The following year, Mr Gulen faced charges of trying to undermine Turkey's
summary: Supporters regard the Hizmet movement inspired by US-based Turkish preacher Fethullah Gulen as the benign, modern face of Islam, but critics question its motives.
