With that declaration, Buhari broke his silence about a rumour that had taken root on social media previous year, when he was away in London being treated for an undisclosed illness.
Videos claiming he was replaced by a clone have been viewed hundreds of thousands of times on YouTube, reported the Sydney Morning Herald.
"I can assure you all that this is the real me".
Speaking from Poland Buhari said: "A lot of people hoped that I died during my ill health".
"Yes, a lot of people had hoped that l was dead and call the Vice President and asked whether he should consider them because they thought l was dead".
"I don't see any serious government responding to that", Muhammad added, arguing that Buhari "remembers memos he had seen or heard about in 1985 and we say he is cloned".
Consultations politiques et premières comparutions judiciaires ce lundi — "Gilets jaunes"
Ce dimanche, un collectif de " Gilets jaunes libres " a lancé un appel au gouvernement via une tribune publiée dans le JDD . L'opposition a sommé le chef de l'État de réagir face à une situation souvent décrite comme "insurrectionnelle".
President Buhari dismissed claims that he was a mystery being, Jubril from Sudan, having died and been cloned.
Buhari also uploaded on Twitter a video of him from the town hall meeting.
The President spoke during his interaction with Nigerians at the Kraków Holiday Inn, Poland, an event put together by Abike Dabiri, Senior Special Assistant to the President on Foreign Affairs and Diaspora, as part of his engagements on the sidelines of the global summit on Climate Change taking place in Poland.
The rumour has been fuelled by high-profile individuals, such as Goodluck Jonathan, Mr Buhari's predecessor, and Nnamdi Kanu, the leader of secessionist group Indigenous People of Biafra (Ipob). Few provide any details regarding who did the cloning and how they successfully managed to create a 75-year-old man during Buhari's absence last year. "After extensive surgery they brought him back".
Oyedepo, therefore, called on President Buhari to address the nation on the issue of being cloned, saying "but if the president wold not address the nation on a subject as sensitive as this, it must have been proved beyond any iota of doubt that maybe he is not our president". "I only get harassed by my grand children because they are getting too many", he said. Meanwhile, the May murder of a Nigerian diplomat in the Sudanese capital of Khartoum became the seed of the weird geopolitical suspicion feeding the rumor. Habibu Almu was found stabbed to death in the Sudanese capital of Khartoum, with a Sudanese woman of Nigerian origin arrested on suspicion of involvement.
Also, a fact check published by AFP last Friday had disproved speculations that Buhari had died and was replaced by a look-alike.
