A man has taken to social media after he was offended seeing a sign reading 'there is no God but Allah' on a western Sydney mosque.

Going by the name 'Joshua Fln' the man took to Facebook to show a photo of the sign he took in Lakemba.

'Took this photo in Bankstown I know it's full of Muslims but don't bring this sign and s**t too [sic] Australia f**kin hang the s**t up in your room not in public,' he posted, accompanied by three photos of the sign.

The man said he 'got stared at like no other going down that street cause [sic] I was white'.

'It's actually really sad we're made to not feel welcome in our own dam [sic] country,' the woman replied.

'Yep 100 [per cent] correct that's what the radical Muslims are trying too [sic] do,' the man then commented.
