A British Muslim says he has been "left stateless" after police seized his passport over claims he wanted to travel to Syria.
The man, who has been asked to be known as Abu Haleema, was woken yesterday morning by anti-terror police raiding his London home.
The officers told the man they were searching for "articles relating to terrorism" and seized his passport.
He was not arrested but was left with a letter from the Home Office detailing their suspicions.
Mr Haleema told ITV News: "They believe I'm involved in terrorism-related activity, which is not true, and that I may have been thinking of going to Syria to fight, which is completely not true."
He described the raid as "a war against Islam" and authorities were "trying to create a climate of fear in the community".
As well as Mr Haleema, his brothers, mother and women and children were in the house at the time of the raid.
The raid was one in a series of counter-terrorism raids that were staged at six addresses in the south of England on Wednesday.
Officers from the Metropolitan Police's anti-terrorism squad SO15 searched properties in High Wycombe in Buckinghamshire; Hounslow in Middlesex; Walthamstow in east London; Brentford in south west London and two in Greenford, west London.
Scotland Yard said the raids were carried out under schedule 5 of the Terrorism Act.
Mr Haleema says the campaign will create "suspicion and fear in the Muslim community".
