Sifat ‘ismah atau pun maksum bagi para nabi dan rasul adalah sangat penting difahami oleh setiap generasi manusia. Ketidakfahaman yang jitu dalam hal ini menyebabkan kebarangkalian wujud persepsi negatif kepada para utusan Allah SWT dan ini merencatkan lagi proses penyebaran Islam secara tidak langsung. Justeru, artikel ini membuat tinjauan secara umum dan melihat secara khusus kepada pandangan Badiuzzaman Said Nursi berkenaan pengertian c ismah (maksum) dan juga melihat kepada hikmah serta tujuan keperluan ‘ismah ini bagi diri para nabi dan rasul. Antara metode penulis dalam kajian ini ialah merujuk langsung daripada kitab-kitab Rasail an-Nur, dan juga melalui sumber-sumber bacaan berkenaan konsep ‘ismah. Perbandingan daripada beberapa aliran pemikiran dalam Islam berkaitan perbahasan ini juga diketengahkan supaya kesamaran konsep ini terangkat dan dapat dijelaskan sebaiknya. Hasilnya, kita dapat mengenal pasti sudut pandang sebenar yang diterima pakai di sisi Ahl al-Sunnah wa al-Jama’ah menerusi perbincangan yang dikemukakan oleh tokoh mujaddid abad ke 20 ini.

Effective da'wah communication is very necessary in maintaining the well -being of the community so that it is always in a state of peace, tranquility and harmony. Niaz Muhammad and Fazle Omer state that the principles of effective da'wah communication should cover all aspects of verbal communication and non -verbal communication. Meanwhile, S. Salahudin Suyurno stated that effective da'wah today must be based on manhaj rabbaniyyah, as emphasized by Allah SWT in surah an-Nahl, verse 125. Both of these things are included in Said Nursi's method of communication when preaching, until it is spread throughout Turkey in particular. Thus, this study focuses on the study of the form of communication Badiuzzaman Said Nursi especially non-verbal communication (non-verbal) while disseminating and delivering the message adapted through his masterpiece that is Rasail an-Nur. The methodology of this study is based on the reference of his own book, the book of Rasail an-Nur as well as the writings of scholars on the communication of his da'wah. The results of the study found that Badiuzzaman Said Nursi's preaching experience in various stages of his life such as in politics, education, war and so on caused him to be loaded with preaching experience with various forms of communication, especially in non -verbal forms. (not verbal), then appointed as a figure of contemporary da'wah and reform, until he was called 'badiuzzaman' which is the excellence of the times.
