President buhari hails shonekan 80
I think there may be a mistake here. Shonekan is not a person who is 80 years old, and I couldn't find any information about President Buhari hailing someone with that name.
However, I think you may be referring to Ernest Shonekan, a Nigerian politician who was the Interim Head of State of Nigeria from August 26, 1993, to November 17, 1993. He was born on May 9, 1936, which would make him around 87 years old.
If that's the case, I couldn't find any information about President Buhari specifically hailing Shonekan on his 80th birthday. But it's possible that President Buhari or other Nigerian leaders may have paid tribute to Shonekan on his birthday or at some other time. If you have any more information or context about this, I'd be happy to try to help you further!
