Jakarta – Convicted terrorist Abu Bakar Ba'asyir launched a book on Sunday in which he condemned government officials and lawmakers for maintaining what he called the rule of infidels.

In the 176-page book, Ba'asyir implored government officials and politicians to return to the true path of Islam before they died.

"The rulers have to replace the law of the land, the positive law of the Unitary State of Indonesia, with sharia," Ba'asyir said in his book.

Ba'asyir wrote portions from the book while he was being held by the National Police. He is currently serving his jail term at the maximum security prison on Nusakambangan Island off the coast of Cilacap, Central Java.

In February 2012, the Supreme Court rejected his appeal, upholding a lower court's 15-year sentence for running a terrorist training camp in Aceh.

The Supreme Court annulled the nine-year prison sentence for Ba'asyir handed down by the Jakarta High Court in October and reinstated the South Jakarta District Court's original 15-year sentence.
