I earned no salary when i was a minister falae
I think there may be some confusion here.
Abdulsalami Abubakar was the Head of State of Nigeria from 1998 to 1999, not Olu Falae. Olu Falae was a Nigerian politician who served as the Secretary to the Government of the Federation from 1995 to 1999, under the administration of General Sani Abacha.
As the Secretary to the Government of the Federation, Olu Falae would have received a salary for his work. It's possible that you may be thinking of a different person or context.
If you could provide more information or clarify what you mean, I'd be happy to try and help you further.
