The letter was written by leaders of these schools across Madura Island in East Java Province.
"We sent a letter to Indonesian President Joko Widodo today," chief of All-Madura Islamic Boarding Schools Association (HP3M) KH Lailurrahman said in a press briefing at Pamekasan Police Precinct here on Friday.
The letter, dated October 26, 2016, was signed by HP3M Chief KH Lailurrahman and his secretary KH Djakfar Shodik.
The ulemas said if the legal process in this case was not followed, it will trigger larger rallies against Ahok, the Jakarta governor who is seeking re-election in February 2017.
In the letter, the ulemas also mentioned several articles in the 1945 Constitution that could form the legal basis for their call, including article 1 para 2; article 1 para 3; article 4 para 1; article 24 para 1; article 27 para 1; and article 30 para 4.
"Article 4 para 1 of the Constitution stipulates that the President of the Republic of Indonesia holds government power in accordance with the law," he noted.
Article 30 para 4 stipulates that the Indonesian police is a state apparatus assigned to keep security and public order, protect and serve the public and uphold the law, he underlined.
He lamented that it seemed the police had not bothered about the case despite widespread protests against the Jakarta governor.
The Indonesian Ulema Council (MUI) has accused Ahok of committing blasphemy when recently making a statement on a verse from the Quran that prohibits Muslims from electing non-Muslim leaders.
MUI chairman Maruf Amin pointed out in a statement that Ahok has insulted the Quran and the ulemas, and that police should investigate the case.
The MUI referred to the statement by Ahok telling people in the Thousand Island not to be deceived by people using the verse asking them not to elect a non-Muslim leader in the forthcoming election. (*)
