The United States released the will Tuesday, part of a cache of 113 documents seized at bin Laden's compound in Abbottabad, Pakistan, when US commandos killed him in a raid almost five years ago.

The last years of al Qaeda leader Osama bin Laden's life were consumed by fears that he was being spied upon and pursued by American forces.

"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.

It is not clear what became of bin Laden's fortune although the US and other governments have devoted significant energy to seizing al-Qaida funds and disrupting its financial-support networks.

The Office of the Director of National Intelligence released dozens of documents, including one they said was bin Laden's will that deals with monies in Sudan.

According to intelligence sources, the second collection of documents, acquired in the 2015 May raid, expose that al-Qaeda was bent on continuing its mission towards what it believed to be "world-wide Jihad", however, inter-leadership terrorist administrations in Pakistan and Afghanistan were strained out.

"I will ask the brother with you to buy you a computer and accessories".

The signed will states bin Laden had about US$29 million (HK$226.2 million) in the country. Among the documents released Tuesday are what appear to be letters to one of those two women, Khairiah Sabar, a former teacher of deaf children in Saudi Arabia who had been under house arrest in Iran.

Researchers looked at data from 1986 of 88,084 women (aged 30-55) and 47,881 men (aged 40-75) participating in two large studies . And for bowel cancer , which affects 41,000 people in Britain every year, the risk of diagnosis was reduced by 19 per cent.

In a letter to one of his wives who lived in Iran, bin Laden expressed worry that her dental appointment could have allowed Iranians to implant a tracking device under her skin. He advised the leader of al Qaeda in Yemen to recruit Yemenis with USA visas or American citizenship to carry out attacks in the States.

Death also appears to have been on his mind. "The size of the chip is about the length of a grain of wheat", he wrote.

Osama wrote hundreds of memos, letters and video messages containing explicit and detailed orders for his lieutenants, along with personal, security-obsessed missives for his family members, declassified files obtained by ABC News show.

Bin Laden warned conflict with regimes in the Middle East would distract the extremists from hitting hard at what, in his opinion, is the real enemy - US. "I promised him that I would reward him if he took it out of the (Sudanese) government".

In a letter dated less than three months before his death, bin Laden wrote that he preferred a female relative to visit a female doctor to describe an unidentified set of symptoms and said an x-ray or ultrasound should be obtained if the symptoms persisted.

He laid out specific amounts in Saudi riyals and gold that should be divided between his mother, a son, a daughter, an uncle, and his uncle's children and maternal aunts.

It was unclear to whom bin Laden was writing, as his natural father, Mohammed bin Laden, died in a 1967 plane crash.
