The Implementation of Takhalli Value in Arabic Grammar according to Al-Qushayri in Na?w al-Qulub al-Kabir

One of the ways to achieve the purification of the soul of a salik in his spiritual journey is through the process of takhalli. The discussion about the process is usually described in Sufism and is rarely discussed in detail in other Islamic disciplines such as Jurisprudence, Tawhid and Arabic. However, given the importance of cross-disciplinary knowledge of Islam, a famous Sufi in the 5th century of Hijra named Abd al-Karim bin Hawazin al-Qushayri produced his work in Arabic grammar which was tailored according to Sufism approaches by applying spiritual values in this discipline. Hence, this study focused on investigating his discussion on the concept of takhall? and its application in several Arabic grammatical topics found in the book Na?w al-Qul?b al-Kab?r. Text content analysis was utilised to obtain necessary data. The study found that the first stage that every s?lik must follow in their spiritual journey is the process of the removal of sins and the abominable traits which become the barrier of receiving the mercy and affection of Allah Ta'ala. Al-Qushayri was seen as a pioneer who successfully applied the values of Sufism in the discussion of the Arabic grammar which is usually discussed solely in linguistic terms. The study concludes that the approach introduced by al-Qushayri should serve as a basis and guidance in applying spiritual values, especially in Arabic grammar subjects at every level of study to make the learning of grammatical knowledge more integrated as not merely correcting verbal language mistakes, however to keep the heart from elements that can tarnish its purity.
