Nishapur or officially Romanized as Neyshabur is the second-largest city of Razavi Khorasan Province in the Northeast of Iran. Nishapur is situated in a fertile plain at the foot of Binalud Mountain Range and has been the historic capital of the Western Quarter of Greater Khorasan, the historic capital of the 9th-century Tahirid dynasty, the initial capital of the 11th-century Seljuk Empire, and is currently the capital city of Nishapur County and a historic Silk Road city of cultural and economic importance in Iran and the region of Greater Khorasan.

Greater Khorāsān, or Khorāsān, is a historical eastern region in the Iranian Plateau between Western and Central Asia. The name Khorāsān is Persian meaning "where the sun arrives from" or "the Eastern Province". The name was first given to the eastern province of Persia during the Sasanian Empire and was used from the late Middle Ages in distinction to neighbouring Transoxiana. Greater Khorasan is today sometimes used to distinguish the larger historical region from the former Khorasan Province of Iran (1906–2004), which roughly encompassed the western half of the historical Greater Khorasan.

A physician, medical practitioner, medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.

Sufism, also known as Tasawwuf, is a mystic body of religious practice, found mainly within Sunni Islam but also within Shia Islam, which is characterized by a focus on Islamic spirituality, ritualism, asceticism and esotericism. It has been variously defined as "Islamic mysticism", "the mystical expression of Islamic faith", "the inward dimension of Islam", "the phenomenon of mysticism within Islam", the "main manifestation and the most important and central crystallization" of mystical practice in Islam, and "the interiorization and intensification of Islamic faith and practice".

Mysticism is popularly known as becoming one with God or the Absolute, but may refer to any kind of ecstasy or altered state of consciousness which is given a religious or spiritual meaning. It may also refer to the attainment of insight in ultimate or hidden truths, and to human transformation supported by various practices and experiences.

Philosophy is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Some sources claim the term was coined by Pythagoras, although this theory is disputed by some. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation.

Abū Yazīd Ṭayfūr bin ʿĪsā bin Surūshān al-Bisṭāmī (al-Basṭāmī), commonly known in the Iranian world as Bāyazīd Bisṭāmī, was a Persian Sufi from north-central Iran. Known to future Sufis as Sultān-ul-Ārifīn, Bisṭāmī is considered to be one of the expositors of the state of fanā, the notion of dying in mystical union with Allah. Bastami was famous for "the boldness of his expression of the mystic’s complete absorption into the mysticism." Many "ecstatic utterances" have been attributed to Bisṭāmī, which lead to him being known as the "drunken" or "ecstatic" school of Islamic mysticism. Such utterance may be argued as, Bisṭāmī died with mystical union and the deity is speaking through his tongue. Bisṭāmī also claimed to have ascended through the seven heavens in his dream. His journey, known as the Mi'raj of Bisṭāmī, is clearly patterned on the Mi'raj of the Islamic prophet Muhammad. Bisṭāmī is characterized in three different ways: a free thinking radical, a pious Sufi who is deeply concerned with following the sha'ria and engaging in "devotions beyond the obligatory," and a pious individual who is presented as having a dream similar to the Mi'raj of Muhammed. The Mi'raj of Bisṭāmī seems as if Bisṭāmī is going through a self journey; as he ascends through each heaven, Bisṭāmī is gaining knowledge in how he communicates with the angels and the number of angels he encounters increases.

Altruism is the principle and moral practice of concern for the welfare and/or happiness of other human beings or animals, resulting in a quality of life both material and spiritual. It is a traditional virtue in many cultures and a core aspect of various religious and secular worldviews. However, the object(s) of concern vary among cultures and religions. In an extreme case, altruism may become a synonym of selflessness, which is the opposite of selfishness.

Chivalry, or the chivalric code, is an informal and varying code of conduct developed in Europe between 1170 and 1220. It was associated with the medieval Christian institution of knighthood; knights' and gentlemen's behaviours were governed by chivalrous social codes. The ideals of chivalry were popularized in medieval literature, particularly the literary cycles known as the Matter of France, relating to the legendary companions of Charlemagne and his men-at-arms, the paladins, and the Matter of Britain, informed by Geoffrey of Monmouth's Historia Regum Britanniae, written in the 1130s, which popularized the legend of King Arthur and his knights of the Round Table. All of these were taken as historically accurate until the beginnings of modern scholarship in the 19th century.

Islam is an Abrahamic monotheistic religion centered around the Quran and the teachings of Muhammad. Adherents of Islam, called Muslims, number approximately 1.9 billion globally and are the world's second-largest religious population after Christians.

Ḥadīth or Athar refers to what most Muslims and the mainstream schools of Islamic thought, believe to be a record of the words, actions, and the silent approval of the Islamic prophet Muhammad as transmitted through chains of narrators. In other words, the ḥadīth are transmitted reports attributed to what Muhammad said and did.
