A Tunisian man who once allegedly protected Osama Bin Laden has lived in Germany since 1997 and gets €1,168 (£1,022) a month in welfare payments.
The figure was revealed by a regional government, after the far-right Alternative for Germany (AfD) asked about the man, known as Sami A.
German media have not reported the man's full name for privacy reasons.
He denies jihadist links. Deportation to Tunisia was ruled out because of fears that he could be tortured there.
Bin Laden ran the al-Qaeda jihadist network and approved the devastating 9/11 terror attacks on the US in 2001. He was shot dead by US special forces in Pakistan in 2011.
