Sin ad Marie Bernadette O’Connor (born 8 December 1966) is an Irish singer-songwriter who rose to fame in the late 1980s with her debut album The Lion and the Cobra. O’Connor achieved worldwide success in 1990 with a new arrangement of Prince’s song “Nothing Compares 2 U.”
Since then, while maintaining her singing career, she has occasionally encountered controversy, partly due to her statements and gestures. These include her ordination as a priest, despite being a woman with a Roman Catholic background, and strongly expressing views on organised religion, women’s rights, war, and child abuse. In addition to her ten solo albums, her work includes many singles, songs for films, collaborations with many other artists, and appearances at charity fundraising concerts.
In 2017, O’Connor changed her name to Magda Davitt. After converting to Islam in 2018, she changed it to Shuhada’ Sadaqat. However, she continues to record and perform under her birth name.
