Hundreds are inviting Saudi Arabia to sue them after the state reportedly threatened legal action against any Twitter user who compares its decision to execute a poet to punishments carried out by Isis.

A source in the country’s justice ministry told the newspaper Al-Riyadh, the department would "sue the person who described… the sentencing of a man to death for apostasy as being 'Isis-like'".

The announcement was prompted by someone on Twitter who compared the Kingdom’s decision to sentence 35-year-old Palestinian poet, Ashraf Fayadh, for apostasy, or renouncing one’s faith, to the punishments handed out by Isis, according to documents seen by Human Rights Watch.

"Questioning the fairness of the courts is to question the justice of the Kingdom and its judicial system based on Islamic law, which guarantees rights and ensures human dignity," the source told the pro-government newspaper.

They claimed the Kingdom’s courts would not hesitate to put on trial "any media that slandered the religious judiciary of the Kingdom".

Saudi Arabia has not yet identified the alleged Twitter user.

The threat has not deterred people from defying the Saudi government, with many taking to the social media site to further liken the Arab country to Isis’s regime.

The hashtag #SueMeSaudi accompanies many messages taunting the government to sue them for supposed libel.

Mr Fayadh has denied the charges and claims another man made false accusations to the country’s religious police following a personal dispute, according to Human Rights Watch.

He has 30 days to file an appeal.

Isis has been accused of executing as many as 10,000 people, according to the Syrian Observatory for Human Rights. However, these figures are extremely difficult to verify.
