The 47-year-old cleric was accused of making such statements during sermons at mosques and in private meetings, reports The Times of London.
Prosecutor David Perry told jurors that Hamza, also known as Mustafa Kamel Mustafa and Abu Hamza al-Masri, frequently gave talks at Muslim meetings and occasionally delivered sermons at Finsbury Park Mosque until it was closed in 2003.
Perry said police discovered 2,700 audio tapes and 570 video tapes when they searched the home of Hamza, who was born in Egypt but is now a British citizen.
