Madaris were largely centred on the study of fiqh (Islamic jurisprudence). The ijazat al-tadris wa-al-ifta' ("licence to teach and issue legal opinions") in the medieval Islamic legal education system had its origins in the 9th century after the formation of the madhahib (schools of jurisprudence). George Makdisi considers the ijazah to be the origin of the European doctorate. However, in an earlier article, he considered the ijazah to be of "fundamental difference" to the medieval doctorate, since the former was awarded by an individual teacher-scholar not obliged to follow any formal criteria, whereas the latter was conferred on the student by the collective authority of the faculty. To obtain an ijazah, a student "had to study in a guild school of law, usually four years for the basic undergraduate course" and ten or more years for a post-graduate course. The "doctorate was obtained after an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." These were scholarly exercises practised throughout the student's "career as a graduate student of law." After students completed their post-graduate education, they were awarded ijazas giving them the status of faqih 'scholar of jurisprudence', mufti 'scholar competent in issuing fatwas', and mudarris 'teacher'.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Islamic law school end?

Question: Antibiotics revolutionized medicine in the 20th century, and have together with vaccination led to the near eradication of diseases such as tuberculosis in the developed world. Their effectiveness and easy access led to overuse, especially in livestock raising, prompting bacteria to develop resistance.
