Mrs Buhari said this in a goodwill message read by the Senior Special Assistant to the President, Dr Hajo Sani, on Sunday, in Abuja.
“I appeal to all Nigerians to show true sense of patriotism for national cohesion to ensure that Nigeria attains the greatness for which it was destined,” she said.
She also urged Nigerians to continue to pray for the president’s well-being.
According to the wife of the president, the Sallah celebration is imperative as it marks the end of the holy month of Ramadan.
“I felicitate with Nigerians and the Muslim Ummah over this opportunity to get closer to Allah,’’ she said.
In his sermon, the Chief Imam of Mambila Barracks Mosque, Major Hamisu Mustapha, admonished Muslims to use the lessons learnt during the Ramadan to foster unity.
