<p>Ustaz Abdul Somad kembali menjadi sorotan khalayak karena dakwahnya yang kontroversial. Pada akhir Agustus 2019, video ceramah Ustaz Abdul Somad yang diunggah pada tahun 2016 yang berjudul “Hukum Melihat Salib” sempat viral di media sosial karena dianggap mengandung unsur Suku, Agama, Ras, dan Antargolongan (SARA). Video pendek yang berisi jawaban Ustaz Abdul Somad atas pertanyaan jamaah, mengandung konten yang menyinggung tentang salib sehingga menimbulkan respon negatif dari umat nonmuslim. Selain itu, ada video ceramah lain yang berjudul “Hukum Menonton Film Korea” yang juga menimbulkan respon negative bagi para penggemar KPop atau KPopers. Tulisan ini fokus pada bagaimana etika komunikasi dakwah Ustaz Abdul Somad yang dibangun berdasarkan perspektif Al Quran. Penelitian ini menggunakan pendekatan kualitatif-deskriptif. Subjek penelitiannya adalah dua video ceramah Ustaz Abdul Somad yang berjudul “Hukum menonton Film Korea” dan “Hukum Melihat Salib”. Sementara objek penelitian ini ialah retorika Ustaz Abdul Somad dalam video-video tersebut. Hasilnya, ceramah dalam kedua video tersebut mengandung prinsip etika komunikasi dalam Al Quran, dengan catatan ceramah tersebut dilakukan pada kelompok terbatas. Etika Al Quran yang dimaksud adalah prinsip bicara tegas dan jujur. Namun, jika dalam konteks media sosial yang bersifat general atau umum, maka pesan dakwahnya tidak sesuai dengan salah satu kode etik dakwah serta dinilai tidak efektif.</p><p> </p><p><em>Ustaz Abdul Somad returned to the media spotlight because of his preaching that triggered a negative response by other groups. At the end of August 2019, Ustaz Abdul Somad's video lecture uploaded in 2016 entitled "Hukum Melihat Salib" was viral on social media because it was considered to contain SARA elements. In the video footage, there is content that is offensive about the cross, giving rise to negative responses from non-Muslim communities. In addition, the lecture video entitled "Hukum Menonton Film Korea" also caused a negative response for KPopers. Therefore, this paper focuses on how the ethics of Ustaz Abdul Somad's missionary communication are built on the perspective of the Qur'an. This research uses a qualitative descriptive approach. His research subjects used Ustaz Abdul Somad's video lecture entitled "Hukum Menonton Film Korea" and "Hukum Melihat Salib". While the object of this research is the rhetoric of Ustad Abdul Somad in the videos. As a result, both videos contain ethical principles of communication in the Koran, if the lecture is aimed at a particular group. Unlike the case in social media that is universal (anyone, anytime and anywhere can be accessed), then the message of preaching is not </em><em>following</em><em> </em><em>one of the preaching code of ethics and has not been effective. </em></p>
