Slain al-Qaeda leader Osama bin Laden bequeathed a personal fortune of $29 million for 'jihad for the sale of Allah', documents released by the US showed.

The 9/11 mastermind's will was among the trove of documents seized in the US raid on is hideout in Pakistan's Abottabad in 2011.

In the document, bin Laden asks his family to "obey my will" and spend the money on furthering the cause of jihad. He mentions the money is in Sudan, but it's not clear if it was in the form of cash or assets.

The Office of the Director of National Intelligence (ODNI) also released dozens of other documents related to bin Laden.

The will was hand-written in Arabic on a single piece of paper and states that he has $29 million stashed away in Sudan, where he lived many years after returning from the anti-Soviet campaign in Afghanistan.

"I received twelve million dollars from my brother Abu Bakir Muhammad Bin (Laden) on behalf of Bin Laden Company for Investment in Sudan," the ODNI's translation of the document read.

"I hope, for my brothers, sisters, and maternal aunts, to obey my will and to spend all the money that I have left in Sudan on jihad, for the sake of Allah."

The released documents also reveal that bin Laden was worried that a dentist had planted a tracking device in his wife's teeth and that he had requested forgiveness from his father.

He was also worried about being assassinated and asked his family to pray for him after his death.

"If I am to be killed, pray for me a lot and give continuous charities in my name, as I will be in great need for support to reach the permanent home," he wrote in a letter.

The tranche of bin Laden documents also reveal he had planned a media campaign to mark the 10th anniversary of 9/11 attacks.

US had released the first tranche of Osama documents in May. Bin Laden was killed by the US Navy Seal Team 6 commandos in an assault on his Abottabad hideout in May 2011.
