Governor Shettima also said the Goodluck Jonathan administration and the PDP era was a tragedy that befell Nigeria.
Shettima said the entire region would have been wiped out by the Boko Haram terrorists if not for the President whom God gave Nigeria at the nick of time.
Speaking at the opening ceremony of a 2-day summit organised by Northern Elders Forum (NEF) in Kaduna, the Governor stressed that Nigerians must unite as a people.
He described the Goodluck Jonathan administration as the greatest tragedy that befell Nigeria, adding that Nigeria was on the brink of collapse under the former President.
"President Buhari is our saviour in North east, his coming saw to the degradation of the Boko Haram sect even though they are not yet completely eliminated," Shettima said.
According to him, at least 50,000 women lost their husbands as a result of Boko Haram activities while the death toll of children is unimaginable.
