The Al-Mukmin Islamic boarding school also known as Pesantren Al-Mukmin and Pondok Ngruki, is a pesantren located in Ngruki, a suburb in the city of Surakarta, Central Java, Indonesia. It was founded 1972 by the alleged 'spiritual head' of Jemaah Islamiah, Abu Bakar Bashir, and by Abdullah Sungkar. Al-Mukmin's activities were initially limited to religious discussion after dhuhr. Following increasing interest, the founders expanded Al-Mukmin into a madrasah and then into a pesantren. It currently houses over 2000 students aged between 12 and 18. A number of people linked to the school have been implicated in a series of SunniIslamist terrorist attacks; the International Crisis Group has described the school as an "Ivy League" for Jemaah Islamiah recruits. Pictures of AK47s are hung in hallways, and a sign above a classroom reads:
"Death in the way of Allah is our highest aspiration."
