Mrs Buhari said the President Muhammadu Buhari administration has started fulfilling its campaign promises.
She said her priority is to ensure the President's administration succeeds, which, according to her, will require a collective effort.
She stated this in Benisheik, one of the liberated towns of Borno State, as she flagged off the distribution of relief items to displaced rural women.
This is Mrs Buhari's first public statement since her controversial BBC interview where she said she will not support the President's re-election in 2019 if he does not rid his government of the 'cabal' in control of it.
She said she is happy that the APC-led government has started fulfilling campaign promises to Nigerians.
She said: "On our campaign promises to Nigerians, especially to the people of Borno State, we thank Almighty Allah for giving us the opportunity of beginning to fulfill these promises.
"That is the essence of being a good leader; when you promise, you try to fulfill your promises.
"That is what we are all after. And what I am after in particular is the success of my husband's administration. And we can’t do it alone, except with the help of the governors, their wives and members of our progressive party and all Nigerians."
Mrs Buhari donated the relief materials to the women under the Get Involved initiative, a sub-component of her pet project, Future Assured.
