Emergency services were called to the mosque in Phyllis Avenue, Peacehaven, at around 9.50pm yesterday, October 4.
A volunteer at Peacehaven Mosque said two men escaped with their lives as a massive fireball engulfed the entrance.
Worshippers had only just left after the last prayer service of the day when the mosque was attacked on Saturday night.

An arson investigation has been launched and police are treating the incident as a hate crime.
A volunteer at the mosque, who wished to remain anonymous, said the community has noticed tensions rising.
“There has been a rise in racism around here recently,” they said.
“It’s a quiet area, there’s only a few Muslim people here.
“Everyone here is affected, it’s a small community of Muslims.
“Our neighbours, who are not Muslims, came out crying.
“We have good relations with everybody who lives around.
“Everyone is obviously scared, we don’t know what’s going to happen.
“Obviously, there are flags around everywhere.
“They don’t bother us, this is England and there should be flags around.

“We have heard reports of increased racism.”
Detective Superintendent Karrie Bohanna said: “This is a fast-moving investigation, and we are urging anyone with relevant information to report it to us.
“This includes anyone with CCTV, ring doorbell, dashcam, and mobile phone footage in the area at the time.
“We understand the concerns this has caused within the community, and the impact that will be felt by the Muslim community as a result.
“There is already an increased police presence at the scene and there are also additional patrols taking place to provide reassurance at other places of worship across the county.
“Sussex Police takes a zero-tolerance approach to hate crime and there is no place for hate across the county.
“If you have concerns for your safety or experience any hate or criminal behaviour, please speak to an officer or contact us online or by calling 101. Always dial 999 in an emergency.”
