Muslims have been posting picures of themselves online with a banner telling people what they are giving up over the next 40 days, using the #MuslimsforLent.
According to Buzzfeed, the initiative was started by Bassel Riche, an American Muslim who wants to challenge negative stereotypes of Islam, in the wake of recent terror attacks in Paris and Copenhagen.
"I think the root problem with anti Islamic sentiment in America and the rest of the world is [a] lack of understanding about Islam. The amount of misinformation about Islam that is presented to people every day creates [these] negative views," he said.
