In 2012, Omar participated in WEYA, an international festival for 1,000 of the world's most talented young poets from 100 different countries. Omar tried to publish her literary works in the
Middle East but was rejected. For many years she wrote under a pseudonym, pretending to be a man. Since 2004, Omar has written poetry and critical essays in the Middle Eastern media on
female genital mutilation,
incest,
sexual assault,
honor crimes,
honor killings,
social control,
oppression of women, and the rights of
homosexuals, the disabled, children and women in patriarchal societies. Omar published a poem in the literary magazine
Kritiker in 2014, entitled "The River of Pain That Continues Its Wandering". She also contributed the poem
Barndommens tavshed (Childhood Silence) in the anthology
Ord på flugt (Words on the run), published by
Danish PEN. The anthology was written by authors and journalists who had all fled war-torn countries. On 30 November 2017, Omar's debut novel
Dødevaskeren was published, for which she received the Readers' Book Prize. Two years later, on 26 November 2019, the sequel
Skyggedanseren was published, which was awarded the booksellers' literature prize, De Gyldne Laurbær. Both of Omar's novels are published by Politikens Forlag, and they have been translated into Swedish, Norwegian, Serbian, Macedonian and French. In 2019, Omar opened the Danish literary event Bogforum in Bellacenteret,
Copenhagen, and has given the opening speech at
CPH:DOX in 2020. In 2020, 'the dead washer' was published in France. Le Point soon claimed the book as one of the 30 most important publications in France in 2020. == Human Rights activism ==
