Joseph Fadelle (born Mohammed al-Sayyid al-Moussawi - Arabic: محمد السيد الموسوي), is a Roman Catholic convert from Islam and a writer born in 1964 in Iraq in a Muslim Shiite family.
He lived his conversion secret for many months, then he told his wife and she decided to follow her husband’s religion.
He had to wait long to be baptized, as the Catholic authorities sought to avoid violating an Iraqi law banning proselytizing.
Fadelle fled Iraq through Jordan, narrowly escaping an assassination attempt organised by his own brothers and uncle, and where a Muslim official of UNHCR (UN High Commissioner for Refugees) falsely accused Fadelle before Western authorities of complicity in the gas attack on Kurds which left 5,000 dead.
In 2014, Fadelle prefaced Interroger l'Islam : 1235 questions à poser aux Musulmans !, authored by Guy Pagès.
