Ĥadīŝ Aĥād Sebagai Sumber Hukum Islam (Pemikiran Imam al-Sarakhsī dan Imam al-Ghazālī, Pendekatan Epistemologi)

Ĥadīŝ aĥād is one of the sources of Islamic law. But in practice, the scholars set different conditions as seen in the thoughts of Imam al-Sarakhsī and Imam al-Ghazālī. Therefore, this study examines the nature of ĥadīŝ aĥād according to both Imams, and their views on the criteria for the use of ĥadīŝ aĥād as the source of Islamic law. This research is done by epistemology approach which is part of a study of philosophy science. The technique of completion of research data is done by library research with the method of data analysis, that is a research according to the contents of both Imam. The data analysis is done by the comparative descriptive method that is, to find the relation between thinking with the same thing with equation and difference which is related to ĥadīŝ aĥād as the source of Islamic law. So the author comes to the conclusion of both Imams mentioned that ĥadīŝ aĥād is obliged to be practiced but doesn’t produce knowledge.The opposite side of their opinion is on the terms of practice. Imam al-Sarakhsī presupposes the fakih narrator, while Imam al-Ghazālī doesn’t because according to him the condition of the transmigrants is not realistic and complicates the practice.The analysis of the metaphysical example of ĥadīŝ aĥād fi'liyyah about ĥadīŝ yellow in the morning prayers indicates that in the ĥadīŝ the metaphysical condition of the jurists doesn’t increase the probability to certainty, and the absence of the fakih narrator doesn’t diminish its worth. Thus, the practice of ĥadīŝ aĥād is sufficient at the level of probability, so the thought of Imam al-Sarakhsī and Imam al-Ghazālī being complementary is not a contradiction.
