In 2017, the blasphemy trial of Basuki Tjahaja Purnama (Ahok) received international attention. In 2016, at a campaign stop during the capital city's gubernatorial election, Ahok stated some citizens would not vote for him because they were being "threatened and deceived" by those using the verse Al-Ma'ida 51 of the Qur'an and variations of it. After a university lecturer, Buni Yani edited the video containing his speech, widespread protests against him ensued, culminating in his controversial imprisonment in May 2017. The Joko Widodo administration responded by banning the Indonesian chapter of Hizb ut-Tahrir. Subsequent government attempts, particularly by the country's intelligence agency (BIN), in curbing radicalism has been called an attack on Islam by some sectarian figures.
