The federation's attorney general, Abubakar Malami, married Nana Hadiza, the president's daughter.
A private Nikkai ceremony was held at the property on Friday, according to sources, and that's when the wedding took place.
The attorney general's third wife after Aisha and Fatima was Nana Hadiza, 41.
Prior to their divorce, Hadiza and Abdulrahman Mamman Kurfi had six children together.
When asked about the wedding, Umar Gwandu, Malami's spokeswoman, remained silent.
After President Buhari won the election in 2015, Malami was appointed as AGF and minister of justice. On August 21, he was reappointed.
