In the years following the authoritative rule of Mahathir Mohamad, Abdullah's leadership style was characterized by calmness and openness, allowing for greater public dialogue. His son-in-law, Khairy Jamaluddin, confirmed his passing at the National Heart Institute and noted his health struggles, including dementia.

Under Abdullah, Malaysians experienced increased political freedoms and a relaxation of press restrictions. Bridget Welsh, a Malaysian politics scholar, remarked on Abdullah’s ability to engage with the nation’s complex issues, as he encouraged discussion among its diverse ethnic groups. However, his laid-back demeanor sometimes attracted criticism, with detractors dubbing him "the sleeping prime minister" due to instances of him dozing off in public.

Although Abdullah’s time in office began with a resounding parliamentary victory, his management style drew contrasts to the dynamic leadership of his predecessor. His legacy remains marked by a commitment to dialogue amid Malaysia's evolving political landscape.
