The woman, 23, was taken to a hospital in Bikaner where she succumbed to burn injuries today, police said.
She was sleeping when neighbour Jeetu sneaked into her room last night and attempted rape on her, police said.
Jeetu, who was later arrested, set the woman ablaze by pouring kerosene when she resisted and raised an alarm.
Her husband, who reached after hearing the screams, also sustained injuries while trying to douse the flames, police said.
The two were taken to a hospital where the woman succumbed to injuries after recording her statement, they said.
