During its formative period, the term madrasah referred to a higher education institution, whose curriculum initially included only the "religious sciences", whilst philosophy and the secular sciences were often excluded. The curriculum slowly began to diversify, with many later madaris teaching both the religious and the "secular sciences", such as logic, mathematics and philosophy. Some madaris further extended their curriculum to history, politics, ethics, music, metaphysics, medicine, astronomy and chemistry. The curriculum of a madrasah was usually set by its founder, but most generally taught both the religious sciences and the physical sciences. Madaris were established throughout the Islamic world, examples being the 9th century University of al-Qarawiyyin, the 10th century al-Azhar University (the most famous), the 11th century Niẓāmīyah, as well as 75 madaris in Cairo, 51 in Damascus and up to 44 in Aleppo between 1155 and 1260. Many more were also established in the Andalusian cities of Córdoba, Seville, Toledo, Granada (Madrasah of Granada), Murcia, Almería, Valencia and Cádiz during the Caliphate of Córdoba.

Another significant issue unique to LaserDisc is one involving the inconsistency of playback quality between different makers and models of player. On most televisions, a given DVD player will produce a picture that is visually indistinguishable from other units. Differences in image quality between players only becomes easily apparent on large televisions and substantial leaps in image quality are generally only obtained with expensive, high-end players that allow for post-processing of the MPEG-2 stream during playback. In contrast, LaserDisc playback quality is highly dependent on hardware quality. Major variances in picture quality appear between different makers and models of LD players, even when tested on a low to mid-range television. The obvious benefits of using high quality equipment has helped keep demand for some players high, thus also keeping pricing for those units comparably high. In the 1990s, notable players sold for anywhere from US$200 to well over $1,000, while older and less desirable players could be purchased in working condition for as little as $25.
How cheaply could an older LaserDisc player be purchased in the 1990s?

Some Western writers claim that the immaculate conception of Mary is a teaching of Islam. Thus, commenting in 1734 on the passage in the Qur'an, "I have called her Mary; and I commend her to thy protection, and also her issue, against Satan driven away with stones", George Sale stated: "It is not improbable that the pretended immaculate conception of the virgin Mary is intimated in this passage. For according to a tradition of Mohammed, every person that comes into the world, is touched at his birth by the devil, and therefore cries out, Mary and her son only excepted; between whom, and the evil spirit God placed a veil, so that his touch did not reach them. And for this reason they say, neither of them were guilty of any sin, like the rest of the children of Adam."
