Al-Qaeda leader Osama Bin Laden left a personal fortune of around $29 m (£21 m) after his death in a raid in 2011, his will shows, reports the BBC.
The will is among a trove of documents released to US media. It was seized in the US assault in Abbotabad, Pakistan.
Bin Laden urged his family to "obey my will" and to spend his inheritance on "jihad, for the sake of Allah".
He referred to the money as being in Sudan, but it is not clear whether it was cash or assets.
Bin Laden lived in Sudan for five years in the 1990s as a guest of the Sudanese government.
It is not known whether any of the money made its way to his heirs.
Bin Laden was killed by US special forces in May 2011 in a raid on his compound in Abbotabad, Pakistan.
The group has since been led by al-Qaeda's former second-in-command, Ayman al-Zawahiri.
