She was born in the village of Darguba in the Lankaran uezd. Her father, Ali kishi, died when she was just eight months old. Hagigat's mother remarried a second time, to a superstitious, devout man. From 1917 Hagigat began attending school in Lankaran. After Azerbaijan became Sovietised, her family moved to Baku. The young Hagigat's passion for opera and the stage arose after she began attending an amateur theatre club in Baku. After the composer Muslim Magomayev tested her voice, he hired her to work at the Azerbaijan Opera Theatre. Thus, despite her family's objections, Hagigat khanim became bound to the opera theatre for life. From 1928 to 1932 she studied in the mugham department of the Azerbaijan State Conservatory, taking lessons from Jabbar Garyaghdioghlu, Seyid Shushinski and Gurban Pirimov. From 1927 to 1952 she was known as a soloist of the Opera and Ballet Theatre and a performer of mugham and our folk songs. Arabzangi ("Shah Ismayil" — Muslim Magomayev), Leyli, Asli, Telli ("Leyli and Majnun", "Asli and Karam", "Arshin Mal Alan" — Uzeyir Hajibeyov), and Shahsanam ("Ashug Garib" — Zulfugar Hajibeyov) are the main stage characters she created. As for Hagigat Rzayeva's film career, she appeared in very few films. She played the role of Aunt Gamar in the film "Stepmother". Aunt Gamar is a negative character in the film. She categorically refuses to accept her son-in-law Arif bringing a new mother for Ismayil, and until the end of the film she remains doubtful that Dilara will become a good mother. Even her line in the film — "I am dead, you are alive. This will not become a mother to Ismayil. A stranger's daughter has never become a mother, and never will." — has been etched into people's memory. She was the mother of the composers Azer Rzayev and Hasan Rzayev.
