Millions of Muslim Facebook users are threatening to quit the social network after Islamic pages were removed.
The 2.5 million protesters have threatened to switch to an Islamic social network 'Medina' if Facebook does not restore the pages by midnight on 21 July.
Among the pages removed by the social networking giant are 'I love Mohammed' and 'Quran Lovers', which Facebook says were used to spam users.
A letter posted by the protesters on the website states: “Although you have attended the world's best communication skills courses you have been most successful in growing great hatred and hostility between you and Muslims around the world, but seriously this time you have caused an almost unrepairable [sic] damage.”
The letter also condemned the 'Everybody draw Muhammad Day' pages that urged users to draw caricatures of the Prophet and led to the site being temporarily banned in Pakistan.
