The death, confirmed by Buhari's former aides Garba Shehu and Bashir Ahmed, has prompted an outpouring of grief across the country and among African leaders.
President Bola Ahmed Tinubu announced a seven-day national mourning period on Sunday, as a mark of respect for Buhari's service and legacy. As part of the observance, all national flags will fly at half-staff throughout the mourning period.
An emergency session of the Federal Executive Council (FEC) has also been convened for Tuesday to honour the former leader's memory and contributions.
Buhari, a military ruler from 1984 to 1985 before returning as a democratically elected president from 2015 to 2023, was known for his austere lifestyle, his strong stance against corruption, and his reputation for discipline and integrity.
Leaders and citizens alike have hailed him as a patriot who dedicated his life to national unity, economic reforms, and the fight against graft.
In a statement, President Tinubu described Buhari as a 'dedicated servant of the nation' whose leadership left a significant imprint on Nigeria's political landscape.
Tinubu emphasised the former president's legacy of reforms and the difficult battles he waged against corruption, insecurity, and economic instability.
Vice President Kashim Shettima has been dispatched to London to coordinate the repatriation of Buhari's remains. Plans are in motion for a state funeral, with the late president expected to be buried in his hometown of Daura, in Katsina State, on Monday, July 14, with full military honours.
Buhari's passing marks the end of an era for many Nigerians who lived through both his military rule and his democratic presidency.
Tributes have been pouring in from political figures, foreign governments, and ordinary citizens, all highlighting his firm commitment to discipline, his modest personal life, and his efforts to steer Nigeria through turbulent times.
