A Tanzanian member of parliament has threatened to place a death curse on all ministers if the government does not do more to fight corruption.
Mr Saidi is fed up with corruption
Masoud Haroub Saidi said he was sickened by government corruption, which is said to be increasing and all other methods had failed.
He told parliament that he would use a Koranic verse to make ministers "drop dead" like locusts.
However, parliamentary officials would not let him carry out his threat.
Mr Saidi, MP for Koani in Pemba Isle, said that he decided to turn to the Koran because as a Muslim he believes that it is the strongest method of punishing corrupt elements.
"When we [Muslims] want to stop things from happening we use Halbadiri - an Islamic death curse.
"Halbadiri cannot harm a clean person. But those people who continue to commit such evil deeds will be affected," he said.
The government has set up a Prevention of Corruption Bureau to combat corruption, but Mr Saidi says government ministers are not doing enough to stop the practice.
He pointed his finger at civil servants who take bribes.
"Ministers are supposed to monitor the performance of their civil servants to combat corruption," he said.
But defending the performance of the anti-corruption body, Minister of State for Good Governance Wilson Masilingi told parliament that there have been 123 cases of corruption had gone to court over the past 18 months and the culprits have received jail sentences.
The government says the public is happy with the way it is fighting corruption and that the donor community has pledged over $29,000 to support the war against the vice.
