A video tape of Osama Bin Laden was found at the former home of a suspected terrorist, the Old Bailey was told.
Mr Rowe was arrested at the Channel Tunnel in France
The recording of the al-Qaeda leader was played at the trial of Andrew Rowe, who denies three charges of having articles for use in terrorism.
The tape was found at his estranged wife's home in Birmingham.
Mr Rowe, 34, of Maida Vale, west London, was arrested at the Channel Tunnel in France in 2003 as he was about to return to Britain.
His luggage included a pair of socks, rolled into a ball, which had traces of explosives.
The prosecution said the socks could have been used to clean a mortar launcher barrel.
Mark Ellison, prosecuting, said he was playing the Bin Laden tape in court so the jury could have an insight into Mr Rowe's mind at the time.
Bin Laden, dressed in military fatigues, was shown sitting and speaking into a microphone to call on "the infidel" to leave the holy land.
Later, 11 September bomber Sheikh Abu al-Abbas in his "living will" called on other young Muslims to give their lives for jihad.
Mr Rowe had also been given four new British passports in seven years, Mr Ellison said.
He added Mr Rowe had visited several places of conflict in that time, including Bosnia.
Mr Rowe had gone with his original passport to Bosnia in 1995 as a volunteer where he said he had been injured in a war zone, the court was told.
The trial was adjourned until Thursday.
