During the 1970s and 1980s, Shabazz continued her volunteer activities.
In 1975, President Ford invited her to serve on the American Revolution Bicentennial Council.
Shabazz served on an advisory committee on family planning for the U.S. Department of Health and Human Services.
In 1984, she hosted the New York convention of the National Council of Negro Women.
Shabazz became active in the NAACP and the National Urban League.
When Nelson and Winnie Mandela visited Harlem during 1990, Shabazz was asked to introduce Winnie Mandela.

Shabazz befriended Myrlie Evers-Williams, the widow of Medgar Evers, and Coretta Scott King, the widow of Martin Luther King Jr. They had the common experience of losing their activist husbands at a young age and raising their children as single mothers.
The press came to refer to the three, who made numerous joint public appearances, as the "Movement widows".
Evers-Williams and King were frequent guests at Medgar Evers College, and Shabazz occasionally visited the King Center in Atlanta.
Writing about Shabazz, Evers-Williams described her as a "free spirit, in the best sense of the word.
When she laughed, she had this beauty; when she smiled, it lit up the whole room."
