On Friday 17th July 2009, corresponding to the 25th of Rajab 1430 Hijri, Hizb ut-Tahrir convened a large gathering following Friday prayers at Masjid Al-Aqsa. Tens of thousands of people attended and banners hung around the sacred precincts called for the return of the Khilafah "Caliphate" which would establish the Deen and unite the Muslims.
