Penelitian ini membahas gerakan dakwah di Kota Bandung melalui Masjid Istiqamah di dekat Pasar Cihapit, Bandung. Masjid yang berdiri tahun 1926 dipengaruhi oleh pemikiran tokoh-tokoh eks Partai Masyumi, diantaranya adalah Isa Anshary, Rusyad Nurdin, E.Z. Muttaqien, serta M. Natsir. Gagasan untuk membentuk kader dakwah dilaksanakan di sebuah masjid kecil sebagai upaya menghadapi pengaruh sekularisme dari budaya barat yang berkembang pada awal masa pemerintahan Orde Baru. Pengaruh dari gerakan dakwah tersebut adalah lahirnya organisasi-organisasi remaja masjid di sekitar Bandung. Kegiatan remaja di lingkungan masjid mendapat sambutan baik di kalangan remaja dan pemuda karena kegiatannya melalui pendekatan populer seperti seni dan olahraga. Gerakan dakwahnya masih berpengaruh pada perkembangan dakwah hingga kini, seperti gerakan organisasi remaja masjid, jilbab dan pesantren kilat anak-anak. Pelatihan kader dakwah Kulliyatul Mujahidin Istiqamah menekankan pada komitmen menegakkan ajaran Islam dan mampu menahan pengaruh kelompok Imam Imran yang lebih menekankan pada konsep kultus kepemimpinan Imam, kelompok Imam Imran melakukan aksi teror pembajakan Pesawat Garuda Woyla di tahun 1981. Pengumpulan bahan kajian ini diperoleh melalui sumber arsip milik Yayasan Istiqamah, wawancara para pelaku untuk melengkapi bukti sejarah dan diverifikasi melalui sumber-sumber koran dan majalah sezaman serta kemudian diverifikasi menjadi fakta yang dituliskan.

This study discusses the da'wah movement in Bandung through the Istiqamah Mosque near Cihapit Market, Bandung. The mosque, which was founded in 1926, was influenced by the thoughts of former Masjumi Party figures, including Isa Anshary, Rusyad Nurdin, E.Z. Muttaqien, and M. Natsir. The idea of forming a da'wah cadre was carried out in a small mosque as an effort to face the secularist influence of western culture that developed at the beginning of the New Order government. The influence of the da'wah movement was the birth of youth mosque organizations in Bandung area. Youth activities in the mosque environment are well accepted by teenagers and youth because their activities are carried out through popular approaches such as arts and sports. The da’wah movement still influences the development of da’wah until now, such as the movement of youth organizations for mosques, headscarves and children's boarding schools. The training for the Kulliyatul Mujahidin Istiqamah da'wah cadres emphasizes a commitment to upholding Islamic teachings and is able to withstand the influence of the Imam Imran group which emphasizes the concept of the Imam's cult leadership, the Imam Imran group commited acts of terror by hijacking of the Garuda Woyla Aircraft in 1981. The collection of this study material was obtained through archival sources, owned by the Istiqamah Foundation, interviewing the perpetrators to complete historical evidence and verified through contemporary sources in newspapers and magazines and then verified into written facts.
