The First Lady has shown gratitude to the president's well-wishers while he was ill in London.
President Buhari returned to Nigeria on Saturday, August 19, 2017, 103 days after he left for London to resume treatment for an undisclosed illness.
Taking to her Twitter account (@aishambuhari) on Monday, August 21, the First Lady tweeted, "As we welcome our dear President back home, I am grateful to Nigerians and well wishers all over the world for their continuous prayers and support.
"May God continue to guide, protect and bless us all and our dear country Nigeria."
Despite the presidency's insistence on the president's good health while he was away, his extended medical vacation generated a lot of controversies and sparked protests that have demanded his resignation, and counter-protests that supported him.
