Upon her return, she was received by Toyin Saraki, wife of the senate president; Pauline Tallen, former deputy governor of Plateau state; Ummu Buratai, wife of the chief of army staff; and Theresa Ibas, wife of the chief of naval staff.

She urged Nigerians not to relent in their prayers and good deed for Nigeria to prosper among the comity of nations.
Aisha also prayed for peace, stability and the progress of Nigeria.
“I thank God for journey mercies, I prayed for Nigeria and Nigerian leaders and we should not relent in prayers and good deed,” she said.
She also expressed her gratitude to Nigerians for their support for President Muhammadu Buhari’s administration, urging them to sustain the tempo.
“I want to use this opportunity to thank all Nigerians for the goodwill and support for my husband and Nigeria in general,” she said.
