"Muslims wish to show that we deeply deplore all kinds of hatred toward Jews, and that we are there to support them. We will therefore create a human ring around the synagogue Saturday, February 21," reads the description on a Facebook event page.
The upcoming gathering, organized by a group of young Norwegian Muslims, is set to be attended by more than 700 people, according to its Facebook page.
"We have received a lot of of support and empathy from many sides and it is heartening. It gives us a signal that we are not alone, and it curbs the fear," Ervin Kohn, head of Oslo's Jewish community told the Osloby newspaper.
On Saturday, two civilians were killed when a suspected Islamist gunman opened fire at a free speech seminar and later outside a synagogue in Denmark's capital, Copenhagen.
According to Danish police, the Copenhagen shootings may have been inspired by a string of terrorist attacks in Paris the previous month, when 17 people were killed in Islamist attacks against the Charlie Hebdo magazine and a kosher supermarket.
