Buhari said this on Friday during a meeting with some Nigerian residents in Makkah, Saudi Arabia, according to presidential spokesman Garba Shehu.

On Monday, Buhari flew from Abuja to Riyadh, Saudi Arabia, to attend the Future Investment Initiative Institute’s investment conference.

Buhari said he will not accept any calls for a “unconstitutional extension” of his presidency during a meeting with Nigerians in Saudi Arabia.

For the remaining “eighteen months or so of my time left,” the president added, “whatever I can do to improve the lives of Nigerians, I will do it for the country.”

“By the Holy Qur’an, I swear that I will serve in accordance with the constitution and will leave when my term is up.” “There will be no ‘Tazarce’ (tenure extension),” Buhari stated.

“I don’t want anyone talking about or campaigning for an unconstitutional extension.” That is not acceptable to me.”

Buhari praised Nigerians in Saudi Arabia for effectively representing the country and projecting a positive image.

He also urged citizens at home to always be fair to his administration, asking critics to compare the security situations in the north-east and south-south in 2015 to the current situation.

“My issue is in the North West, where people are murdering and robbing one another.” “I had to be tough on them, and I’ll keep being tough on them until we get them in line and restore order,” he said.
