The author and activist, who was subject to a fatwa in 2000, has won the prestigious prize for translated fiction with her translator Deepa Bhasthi for her collection of short stories about the lives of Muslim women. They explain why Heart Lamp’s themes ‘are universal’

• ‘Radical translation’ of Heart Lamp by Banu Mushtaq wins International Booker prize

‘Human beings and their basic nature are the same everywhere,” Banu Mushtaq says. “That is the intention of my writing. The theme is woman, the theme is marginalised people, the theme is to be a voice to the voiceless community.”

Mushtaq, from the Karnataka region of southern India, has been “awake all night”, she says, as we speak on the morning after she won the International Booker prize in London for her book Heart Lamp. The prize is shared between Mushtaq and her translator Deepa Bhasthi, who is also present – and also had no sleep.
