Ruwan Bagaja Hausa pronunciation: [Ruwan Bagaja] ⓘ literally meaning "Water of Cure" is a debut novel written in Hausa language by Dr Abubakar Imam at the age of 22 years, He presented the book during a literature bureau competition organised by Rupert East in the year 1933 in Zaria.

Abubakar Imam won second prize for his presented book,[1] thus marking his territory as an author to contend with.

With the acclaim from Ruwan Bagaja, he went on to publish nearly 20 other Hausa books including the celebrated three-volume collection of stories Magana Jari Ce.

He settled in Zaria for six months where he wrote the novel Ruwan Bajaga as his debut novel to present in the contest in the year 1933.

At some point, he was told that no human had ever been able to reach it for centuries and due to this dry spell without actual contact with it, the reality of Ruwan Bagaja slowly faded away into a myth, becoming a fairy tale as if it never existed.
