A Canadian author will become the first Muslim-born woman to lead a mixed-gender British congregation through Friday prayers tomorrow in a highly controversial move that will attempt to spark a debate about the role of female leadership within Islam. Raheel Raza, a rights activist and Toronto-based author, has been asked to lead prayers and deliver the khutbah at a small prayer session in Oxford. She has been invited by Dr Taj Hargey, a self-described imam who preaches an ultra-liberal interpretation of Islam which includes, among other things, that men and women should be allowed to pray together and that female imams should lead mixed congregations in prayer.
