The president, in a statement by his spokesman, Femi Adesina joined family members, friends and associates of the former Head of State in celebrating the milestone.
He noted with delight the historic roles Abubakar played in the unity and peace of Nigeria, and in laying the building blocks of democracy.
Buhari also noted the meritorious service of the former Chief of Defence Staff, sacrificing for the country and African continent by participating in peace missions and negotiating for the upholding of democracy across the continent.
He extolled the humility and humanity of the Army General, who chose the noble path by ensuring transition to democratic government in 1999, and midwifed a peaceful handover process in 2015.
