It was reportedly founded by former members of the Jamaat-e-Islami, with whom it came into conflict over management of the East London Mosque "throughout the late 1980s"[10] resulting in "two High Court injunctions" in 1990 in "response to violence" at the mosque.[11] Dawat'ul Islam is now based at another mosque, Jamiatul Ummah Bigland Street.[3]
