Input: Article: However, the classification of madaris as "universities" is disputed on the question of understanding of each institution on its own terms. In madaris, the ijazahs were only issued in one field, the Islamic religious law of shariah, and in no other field of learning. Other academic subjects, including the natural sciences, philosophy and literary studies, were only treated "ancillary" to the study of the Sharia. For example, a natural science like astronomy was only studied (if at all) to supply religious needs, like the time for prayer. This is why Ptolemaic astronomy was considered adequate, and is still taught in some modern day madaris. The Islamic law undergraduate degree from al-Azhar, the most prestigious madrasa, was traditionally granted without final examinations, but on the basis of the students' attentive attendance to courses. In contrast to the medieval doctorate which was granted by the collective authority of the faculty, the Islamic degree was not granted by the teacher to the pupil based on any formal criteria, but remained a "personal matter, the sole prerogative of the person bestowing it; no one could force him to give one".

Now answer this question: What is considered the most famous madrasa?

Output: al-Azhar

Input: Article: Over New York City in 1953, Eastern Airlines Flight 8610, a commercial flight, had a near miss with Air Force Flight 8610, a Lockheed C-121 Constellation known as Columbine II, while the latter was carrying President Eisenhower. This prompted the adoption of the unique call sign Air Force One, to be used whenever the president is on board any US Air Force aircraft. Columbine II is the only presidential aircraft to have ever been sold to the public and is the only remaining presidential aircraft left unrestored and not on public display.

Now answer this question: What call sign does an Air Force aircraft have when a president is traveling on it?

Output: Air Force One

Input: Article: In practice, the emphasis on strictness has resulted in the rise of "homogeneous enclaves" with other haredi Jews that are less likely to be threatened by assimilation and intermarriage, or even to interact with other Jews who do not share their doctrines. Nevertheless, this strategy has proved successful and the number of adherents to Orthodox Judaism, especially Haredi and Chassidic communities, has grown rapidly. Some scholars estimate more Jewish men are studying in yeshivot (Talmudic schools) and Kollelim (post-graduate Talmudical colleges for married (male) students) than at any other time in history.[citation needed]

Now answer this question: Haredi Jews do not share what with other jewish sects?

Output:
doctrines
