Title:
Madrasa

Context:
Much of the study in the madrasah college centred on examining whether certain opinions of law were orthodox. This scholarly process of "determining orthodoxy began with a question which the Muslim layman, called in that capacity mustaftī, presented to a jurisconsult, called mufti, soliciting from him a response, called fatwa, a legal opinion (the religious law of Islam covers civil as well as religious matters). The mufti (professor of legal opinions) took this question, studied it, researched it intensively in the sacred scriptures, in order to find a solution to it. This process of scholarly research was called ijtihād, literally, the exertion of one's efforts to the utmost limit."

Question:
What determination of the study of law was held to much debate?
