Brother this is just a threat to create a psychological scare. The one's creating this type of scare know very well that Muslims are all on Social Media and any Islamophobic news gets spread like fire on the Social Media and through other mediums like forums and youtube etc.
When we spread such news on forums and social media, we're actually helping them spread this scare without us even realizing .
Be careful and don't worry when you hear such news. Just ignore. Islamophobia has always been and will always be, but has it succeeded in stopping or putting an end to Islam? I don't think so.
