This is coming after rumours of his deteriorating health.
The president told his children to be self- reliant, noting that he would leave behind very little for them to inherit.
He said this in his biography written by American Professor, John Paden, titled “Muhammadu Buhari: The Challenges of Leadership in Nigeria.
“Buhari insisted that all of his girls continue their education through the tertiary level.”
According to the book: “This they did, although one continued in higher education after she was married. He told them explicitly that education would give them self-reliance, and that he would not have much in the way of an inheritance to leave to his family.
“Today, Buhari's entire family are not only well educated but also speak English, and are comfortable within the broader Nigerian and international context.”
It is difficult to know the president's worth since the president is yet to make full details of his assets public.
On September 3, 2015, Senior Special Assistant to the President on Media and Publicity provided snippets of information regarding his declared assets.
According to a press statement by Garba Shehu, President Buhari had N30 million in his bank account before taking office on May 29 adding that the president owns five houses in Kaduna, Daura, Kano and Abuja, and has two undeveloped plots of land, one in Kano and the other in Port Harcourt.
He said he also has farms, an orchard, ranch, livestock, including 270 cattle, 25 sheep, five horses, a variety of birds and a number of economic trees
Also according to the statement,President Buhari has one bank account (with the Union Bank), no foreign account, no factory, no enterprises, and no oil wells, the statement said.
It said the president has shares in Berger Paints, Union Bank and Skye Bank. Two of his houses in his native Daura are mud-made, the statement said.
