Ahamada's father is Comorian[2][3] and his mother is from La Réunion from European descent ("Petit Blanc des hauts").[4] The family moved to Marseille when Saïd Ahamada was a baby.[4]
From 18 June 2017, Ahamada was a member of the National Assembly for the 7th constituency of the Bouches-du-Rhône department, which includes part of the 14th arrondissement of Marseille as well as its 15th and 16th arrondissements (the "Quartiers Nord").[3] In parliament, he served as member of the Finance Committee. In addition to his committee assignments, he was part of the French-Algerian Parliamentary Friendship Group.[6]
In early 2018, Ahamada was one of several LREM members who joined an informal parliamentary working group on Islam set up by Florent Boudié in order to contribute to the government's bill aimed at better organising and supervising the financing of the Muslim faith in France.[7]
From 2019, Ahamada served as one of his parliamentary group's spokespersons under the leadership of its chairman Gilles Le Gendre.[8]
