AbstractManuscripts are cultural and historical heritage that contain handwriting, such as Javanese script, Pegan, etc. In Indonesia there are various ancient manuscripts, one of which is the Al-Qur'an mushaf. In accordance with the ijtihad of the ulama, the manuscripts of the Al-Qur'an were written in the Ottoman pattern. Rasm refers to the writing of the Al-Qur'an which is done in a special way, both in writing the pronunciations and in the shapes of the letters used. Meanwhile, the Ottoman rasm is a written, mushaf of the Al-Quran attributed to the caliph Uthman bin Affan which aims to equalize the reading and writing of the Al-Qur'an. However, some Al-Qur'an manuscripts do not use the Ottoman script as a writing guide, such as the Al-Qur'an manuscript stored in the Asasi Padang Panjang mosque. Therefore, it is important to carry out research on rasm, because many people think that the writing of the Al-Qur'an is impossible to bear because its authenticity is guaranteed, and as a form of cultural preservation because manuscripts are part of the cultural and historical heritage of mankind. This research aims to identify the rasm aspects contained in the Al-Qur'an manuscripts of the Asasi Padang Panjang mosque, then compare them with the Indonesian printed Al-Qur'an. The research results show that the use of rasm in this manuscript is inconsistent and uses two different rasm, namely Ottoman and Imla`i. The method used in this research is a qualitative method with a library research model.
