[1][2] Born 5 March 1905 in the village Khasanovo of Pugachev district in Samara province into a peasant family.
During the Civil War in Russia (1918–1920), Hadiya became one of the first Komsomol (Youth organization) members in the district.
From the age of 15, Hadiya Ilyasova began to work as a teacher in the neighboring village of Dengizbaevo.
In 1922, at the age of 17, she married her fellow countryman Gubay Davletshin, who then worked in the Samara Provincial Committee.
In 1933, with her husband, Gubai Davletshin, Hadiya left for the Baymak district in the south of Bashkortostan, where she worked as an employee of the regional newspaper.
Everywhere where Davletshins lived, their house was open to friends, relatives, fellow countrymen who needed help.
One of them, the orphan girl Fatima Mustafina, later became the Minister of Education of the Bashkir Autonomous Soviet Socialist Republic.
The life of the Bashkir people has been shown for two decades against a broad background of social and political events taking place in Russia at the beginning of the 20th century.
The use of the wealth of oral folklore, the colorfulness and richness of the language, the epic scale made the novel a classic work not only of Bashkir, but also of all Oriental and Turkic-speaking literature.
Speaking at the First Congress of Writers of the RSFSR in 1958, Leonid Sobolev said: "Without knowing Hadia Davletshina's novel Irgiz, one cannot understand the reality of the Bashkir people."
Hadiya Davletshina, as a "member of the family of the enemy of the people", was sentenced to five years in prison, which she spent in Mordovia.
On 20 March 1951, Hadiya Davletshina wrote a letter to the chairman of the board of the Union of Writers of the USSR, Alexander Fadeev, in which she asked for help with the publication of the novel.
In Birsk, after some time, Hadiya married Safin, who took care of her and managed to extend her life a bit.
In 1967, for the novel "Irgiz", the writer posthumously became the first laureate of the Republican Prize of the Bashkir Autonomous Soviet Socialist Republic named after Salawat Yulayev .
After the death of writer, her mother Guliaohar (blind) gave Hadiya`s manuscripts to people who promised to publish them.
