Sahih al-Bukhari is considered as the most authentic book of hadith. One of the important aspects in the hadith study is the hadith understanding. Contextual approach is one of the approaches in the hadith understanding. The Islamic scholars have written several books of commentaries in order to explain the hadith content based on its context. However, recent research shows that the hadith understanding level for the Muslim remains in at very moderate level. Previous researches show that existing contextual understanding of hadith are limited in method of qawli, mawdhu’i and muzawwaj. In this paper, a classification that grouped the contextual understanding of hadiths has been proposed in order to overcome this problem. This research focuses on the classification of hadith fi’li in Sahih al-Bukhari based on the Pillars of Islam. Qualitative approach that uses contextual analysis with aim to improve the level of hadith understanding was applied. The phases included the process of selecting hadith fi’li related to word “basara” in Sahih al-Bukhari, extracting their contextual understanding, and finally grouping them into the classifications based on the Pillars of Islam. This classification has five classes namely syahadah, solat, saum, zakat, haj. Based on the results, the contextual understanding of selected hadith involves three classes which are syahadah, solat and zakat.

Hadith which defined as the speeches, actions, tacit approvals and characteristics of Prophet Muhammad PBUH requires thorough attention in understanding. One of the principles in comprehending hadith is by understanding the content contextually, and it could be done by gathering related hadith under a certain concept. Ontology could play the role in the enhancement of this particular principle. However, the usage of ontology in the field of hadith is still limited due to various books of hadith available. Furthermore, the existing hadith ontology has only been focusing on the method of narration section. Thus, this study aims to propose an ontology based on hadith. Apart from that, it intends to explain the context of hadith prior to ontology creation. In order to achieve these objectives, several phases have been conducted to expand the understanding of hadith. The word Samica which means hearing has been chosen as a sample in this approach. The phases involved were the identification of the noun form of the word Samica, the extraction of hadith with the word Samica, the analysis of hadith based on several commentaries books, as well as the development of the ontology. The results indicated that the hadith could be categorized into several concepts which are Allah, Belief, and Sharicah. Allah, Belief and Sharicah have been recognized as crucial concepts in Islamic knowledge. In summary, ontology could be utilized in expanding hadith understanding. � 2017 American Scientific Publishers All rights reserved.
