WHAT WE ALREADY KNOW:

Security has been beefed up and business areas and shopping malls are being secured as the large-scale anti-Ahok rally begins on Friday.

The rally has been organised by Muslim hardliners, mainly by The Islamic Defenders Front (FPI), against the city's Chinese Christian governor Basuki Tjahaja Purnama, popularly known as Ahok.

Governor Ahok was highly condemned for allegedly misquoting a verse from the Quran during one of his speeches in September. During the speech, Ahok criticised his opponents for citing a verse in the Quran which warns Muslims against forming an alliance with Christians and Jews saying that they were "lying". This led to an outrage and the governor was accused of criticising the Islamic holy text.

Meanwhile, the situation in Jakarta is tense as people fear that the rally will not only spur ethnic and religious tensions in the country but also jeopardise next year's much-anticipated Jakarta gubernatorial race, in which Ahok is seeking a second term.

However, President Widodo assured the citizens about safety and encouraged them to go to work and school as usual on Friday.

"Those who work, go to work as usual and those who go to school, go to school as usual," said Jokowi and Vice President Jusuf Kalla as reported by The Jakarta Post.

Moreover, the country's top Islamic clerical body and the two largest Muslim groups have urged people to boycott the protest.

After a meeting with the president, Nahdlatul Ulama Supreme Council chairman Ahmad Ishomuddin urged people not to participate in the rally saying, "Muslims should avoid the rally and not create troubles. We hope the demonstration will pass peacefully. We certainly don't want any casualty."

It is also reported that several people have put up banners on overhead bridges calling for Indonesians to respect diversity. "Your religion or ethnicity doesn't matter, as long as you can do something good for everybody," said one banner, according to Channel News Asia.

Hashtags like #wearenotafraid (#kamitidaktakut) and #peaceaction411 (#aksidamai411) are trending on Twitter as people call for peace and ask the public to avoid any extremist movement.
