Campaigns for the presidential and regional elections in Comoros on Sunday will finish on Friday. Some presidential candidates want people to not vote.
Current President Azali Assoumani is running for a fourth term and has five people competing against him.
For months, some of the people running for office have said they might not participate in the election because they are worried about the fair treatment of political prisoners and if the election is going to be fair.
Mr Assoumani, who is 65 years old, used to be in the military. He became the leader after a coup in 1999.
Both President Assoumani and the electoral body CENI have promised that the election will be fair and open.
Over 300,000 people can vote in the small group of African islands. The total population, estimated by the World Bank, is 836,000.
