While attending secondary school in Johor Bahru, Rahah was introduced to Abdul Razak Hussein, who was an active member of the United Malays National Organisation (UMNO).

As the prime minister's spouse, she served as President of the Girl Guides Association of Malaysia and patron of the Muslim Women's Action Organisation (Pertiwi).

[1] Since Abdul Razak was the prime minister who established diplomatic relations with the People's Republic of China, all PRC ambassadors made a courtesy call on Rahah upon arriving in Malaysia.

[4][5][6][7] Former Prime Minister Mahathir Mohamad described Tun Rahah as among the last from the independence generation who contributed invaluable services and sacrifices for the country.

[9][10] She was laid to rest at the Makam Pahlawan (Heroes' Mausoleum) near Masjid Negara, Kuala Lumpur beside the grave of her sister Tun Suhailah Mohamed Noah, who died on 4 October 2014.
