Greater Iran refers to a sociocultural region in which Iranian traditions and Iranian languages have had a significant impact. It spans parts of Western Asia, the Caucasus, Central Asia, South Asia, and Xinjiang. The region is defined by having been long-ruled by the dynasties of various Iranian empires, under whom the local populaces gradually incorporated some degree of Iranian influence into their cultural and/or linguistic traditions; or alternatively as where a considerable number of Iranian peoples settled to still maintain communities who patronize their respective cultures, geographically corresponding to the areas surrounding the Iranian plateau. It is referred to as the "Iranian Cultural Continent" by Encyclopædia Iranica.

Persian, also known by its endonym Farsi, is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, namely Iranian Persian, Dari Persian and Tajiki Persian. It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivation of the Arabic script, and within Tajikistan in the Tajik alphabet, a derivation of the Cyrillic script.

Fanaa in Sufism is the "passing away" or "annihilation". Fana means "to die before one dies", a concept highlighted by famous notable Persian mystics such as Rumi and later by Sultan Bahoo. There is controversy around what Fana exactly is, with some Sufis defining it as the annihilation of the human ego before God, whereby the self becomes an instrument of God's plan in the world (Baqaa). Other Sufis interpret it as breaking down of the individual ego and a recognition of the fundamental unity of God, creation, and the individual self. Persons having entered this enlightened state are said to obtain awareness of an intrinsic unity (Tawhid) between Allah and all that exists, including the individual's mind. This second interpretation is condemned as heretical by orthodox Islam.

Muhammad was an Arab religious, social, and political leader and the founder of Islam. According to Islamic doctrine, he was a prophet divinely inspired to preach and confirm the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets. He is believed to be the Seal of the Prophets within Islam. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings and practices forming the basis of Islamic religious belief.

Arabic is a Semitic language spoken primarily across the Arab world. Having emerged in the 1st century, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece.

Asceticism is a lifestyle characterized by abstinence from sensual pleasures, often for the purpose of pursuing spiritual goals. Ascetics may withdraw from the world for their practices or continue to be part of their society, but typically adopt a frugal lifestyle, characterised by the renunciation of material possessions and physical pleasures, and also spend time fasting while concentrating on the practice of religion or reflection upon spiritual matters. Various individuals have also attempted an ascetic lifestyle to free themselves from addictions, some of them particular to modern life, such as money, alcohol, tobacco, drugs, entertainment, sex, food, etc.

Dhikr is a form of Islamic meditation in which phrases or prayers are repeatedly chanted in order to remember God. It plays a central role in Sufi Islam, and each Sufi order has usually adopted a specific dhikr, typically accompanied by specific posture, breathing, and movement. In Sufi Islam, dhikr refers to both the act of this remembrance as well as the prayers used in these acts of remembrance. Dhikr can be performed in solitude or as a collective group. It can be counted on a set of prayer beads or through the fingers of the hand. A person who recites the Dhikr is called a Dhakir , literally "he who remembers." The content of the prayers includes the names of God, or a dua taken from the hadiths or the Quran.

Names of God in Islam are names attributed to God in Islam by Muslims. Some names are known from either the Quran or the hadith, while others can be found in both sources.

The Naqshbandi is a major Sunni order of Sufism. Its name is derived from Baha-ud-Din Naqshband Bukhari. Naqshbandi masters trace their lineage to the Islamic prophet Muhammad through Abu Bakr, the first Caliph of Sunni Islam and Ali, the fourth Caliph of Sunni Islam. It is because of this dual lineage through Ali and Abu Bakr through the 6th Imam Jafar al Sadiq that the order is also known as the "convergence of the two oceans" or "Sufi Order of Jafar al Sadiq".
