The Qur'an and hadith are the main sources of reference for determining the legal status in Islam. Both of these references are preserved their originality in written and memorized form. However, the process of memorizing the Qur’an becomes easier compared to the process of memorizing hadith because Allah S.W.T has made it easier for the Quran to be read, memorized and studied as compared to hadith. To know the authenticity of a hadith requires sanad, matan and narrator which musalsal to the Prophet S.A.W. Thus, memorizing a hadith is more complicated than memorizing the Qur'an. Therefore, to facilitate the memorization process requires a unique method that can help students remember and memorize the hadith. Among the methods used in the process of memorizing hadith is by using the method of naẓam.
