According to Buhari's spokesman Femi Adesina, President Buhari has written the National Assembly over the move, however, he did not specify a date for the retired military generals' return.
The statement released by Adesina minutes ago read:
PRESIDENT BUHARI EXTENDS VACATION, WRITES NATIONAL ASSEMBLY
President Muhammadu Buhari has written to the National Assembly today, February 5, 2017, informing of his desire to extend his leave in order to complete and receive the results of a series of tests recommended by his doctors.
The President had planned to return to Abuja this evening, but was advised to complete the test cycle before returning. The notice has since been dispatched to the Senate President, and Speaker, House of Representatives.
Mr. President expresses his sincere gratitude to Nigerians for their concern, prayers and kind wishes.
This development will definitely shoot up rumors about the president's health once again.
