In what could be seen as a reply to the US Republican presidential candidate Donald Trump's call to ban Muslims from entering the US, Facebook CEO Mark Zuckerberg has welcomed Muslims to be part of the social giant and its growing users' community.

In a post on Wednesday, the Facebook founder wrote: "I want to add my voice in support of Muslims in our community and around the world".

"After the Paris attacks and hate this week, I can only imagine the fear Muslims feel that they will be persecuted for the actions of others," he added.

Zuckerberg, who was blessed with a girl child recently, urged the world not to "succumb to cynicism".

"If you are a Muslim in this community, as the leader of Facebook I want you to know that you are always welcome here and that we will fight to protect your rights and create a peaceful and safe environment for you," he posted.

"As a Jew, my parents taught me that we must stand up against attacks on all communities. Even if an attack isn't against you today, in time attacks on freedom for anyone will hurt everyone," he continued.

Trump, the Republican front-runner for the November 2016 presidential election, has proposed banning Muslims from entering the US.

Zuckerberg further wrote: "Having a child has given us so much hope, but the hate of some can make it easy to succumb to cynicism. We must not lose hope".

Facebook has been receiving some criticism for local censorship laws, especially in the Middle East.

But Zuckerberg reiterates that Facebook will remain a home for people of all faith and beliefs.

"As long as we stand together and see the good in each other, we can build a better world for all people," he added.
