Early life
Rahim was born in Belfort, France, into a family that had immigrated from the region of Oran, Algeria.

After earning a Baccalauréat at the Lycée Condorcet of Belfort, Rahim enrolled first in sports and then computer science programmes. After two subsequent years of boredom studying the subjects in Strasbourg and Marseille, Rahim decided to pursue his passion and began to study film at the Paul Valéry University of Montpellier. His life as a film student was chronicled in a documentary by fellow Belfortain Cyril Mennegun titled "Tahar, student", aired on French TV channel France 5 in 2006.

Following this, Rahim moved to Paris in 2005 and studied drama at the Laboratoire de l'Acteur under Hélène Zidi-Chéruy while working in a factory during the week, and in a nightclub at weekends, to make ends meet.
