A source in the Abuja Bureau of the BBC told Daily Trust that there was a letter from the Presidency asking the Hausa service of the BBC not to air the interview.
The Speaker of the House of Representative, Yakubu Dogara, according to the source, also tried to informally dissuade the BBC from airing the interview.
A son of Buhari's powerful nephew, Mamman Daura, is said to have called to get the BBC not to it.
In the controversial interview Aisha Buhari had said those who worked for the president have been abandoned for those who don't even have voters card.
She also expressed fear of rebellion from the fifteen million people who voted her husband.
However, the source told Daily Trust, the BBC wouldn't backdown on its promise to air the interview as an independent media organisation.
The only condition that can make the service not air the interview is for the interviewee, Mrs Buhari, to decide against it. Even in that case her voice recanting what she had said would be aired.
Therefore, a part of the interview will be aired in the service's morning broadcast tomorrow. It will be aired in full on its programme, 'Gane Mini Hanya', on Saturday.
