Kashf (Arabic: كشف) "unveiling" is a Sufi concept dealing with knowledge of the heart rather than of the intellect. Kashf describes the state of experiencing a personal divine revelation after ascending through spiritual struggles, and uncovering the heart (a spiritual faculty) in order to allow divine truths to pour into it. Kashf is etymologically related to mukashafa "disclosure"/ "divine irradiation of the essence",[1] which connotes "gain[ing] familiarity with things unseen behind the veils".[2] For those who have purified their hearts, and who come to know the Divine Names and Attributes to the fullest of their individual capacities, the veils in front of the purely spiritual realms are opened slightly, and they begin to gain familiarity with the unseen. In Sufism, an even further revelatory capacity exists by which the Divine mysteries become readily apparent to the seeker through the light of knowledge of God. This is called tajalli "manifestation".[3]
Two passages in the Qur'an serve as the most solid basis for elaboration on the Sufi concept of kashf:
The verb "kashafa," but never the noun "kashf" occurs in the Qur'an a variety of times in the sense of either "to uncover" (a part of the body) or "to take away" (misfortune, danger).[1]
Hadith of the Veils
One hadith holds particular significance for the concept of kashf:
This Hadith is quoted somewhat differently by Ibn Majah as follows:
It is said that Muhammad's cousin Ali ibn Abi Talib prayed:
Al-Kushayri expands on al-Kalabadhi’s proposal that tajalli (manifestation) of "the essence" of the Divine is called mukashafa. He then illustrates three stages in progression towards understanding the Real:
Al-Ghazali—This Sufi scholar discusses the concept of kashf, not purely in its mystical sense, but also with respect to theology in general. In conjunction with Al-Kushayri, Al-Ghazali links kashf with intuition. For Al-Ghazali, mukashafa has a dual sense:
Since, for Al-Ghazali, kashf is linked to intuition, he describes mukashafa as the certain knowledge of the unseen discovered by the "science of the saints".[1] Thus, kashf is considered "a light," that is freely bestowed upon the purified worshipper through the grace of God, yet also yields sure intuitive knowledge for the worshipper upon whom it is bestowed.
Ibn Arabi—This Sufi mystic indicates the necessity for "divine unveiling" (kashf) as the means by which to understand the universality of the reality of realities (i.e. the universality of God's oneness). In fana (self-annihilation), the individual ego passes away and divine self-manifestation occurs. This self-manifestation is eternal (as it comes from God), but it must be continually reenacted by the human in time. Therefore, the human becomes a pure receptor required for pure consciousness to be realized. The human is a sort of barzakh or intermediary between divinity and elementality, between spirit and matter, and open to the experience of kashf.[5]
Ali Hujwiri—The author of the Persian Sufi text Kashf ul Mahjoob (Revelation of the Veiled) Hujwiri argues, along with Al-Kushayri that very few real Sufis exist anymore in his time; rather, there are a large number of "false pretenders" which he calls mustaswif—"the would-be Sufi". In his text, Hujwiri describes the "veils which should be lifted" in order to purify one's heart and really pursue Sufism. Hujwiri argues for the importance of "morals" over "formal practice" in Sufism.[6] He was the first to directly address the problematic diversity in Muslim belief during his time. In Kashf ul Mahjoob, he describes various Sufi approaches to theoretical ideas, linking them to particular key Sufi figures.[7]
In Shi’ism, the spiritual experience of kashf is treated as a theological rather than purely mystical dimension.
Imamis—Sayyid Haydar Amuli distinguishes three kinds of knowledge: 1) by the intellect, 2) by transmission, 3) by kashf—this is the only form of knowledge that leads to true understanding of Reality
Amuli additionally distinguishes between two kinds of kashf:
Ismalis—these followers of Shi’ism put emphasis on kashf in a double sense as both a Gnostic and cosmic "state." The Ismailis define "cycles of metahistory"[1] which alternate between phases of "unveiling" (dawr al-kashf) and "occultation" (dawr al-satr).
The concept of kashf remains controversial in the Muslim world because it indicates the ability to "know" the unknowable. According to the Qur'an, Muslims are required to believe in the unseen (namely Allah), but knowledge of the unseen is a power that should belong solely to God. But it does not contradict the Qur'an because only God has knowledge of the unseen and if someone else other than God has that knowledge, then it's only because it was given to them by God.
Sufis further would argue that "the only guide to God is God Himself".[8] They do believe that every genuine worshipper has the capability to experience unveiling (personal revelation), but that this personal revelation occurs by the grace of God. Some say, if a worshipper fails to experience unveiling, "it indicates that that person is pursuing Sufism for a reason other than the love of God alone." Ibn ‘Arabi calls this "inner receptivity"[9] to the manifestation (tajalli) of the divine mysteries, the essence of which is mukashafa.
Peripatetic scholars such as Avicenna, al-Kindi, and al-Farabi argue that the intellect unaided by divine unveiling (kashf) is sufficient in order for man to attain ultimate truth.
Sufis such as Bayazid Bastami, Rumi, and Ibn al-Arabi, hold that the limited human intellect is insufficient and misleading as a means of understanding ultimate truth. This kind of understanding requires intimate, direct knowledge resulting from the removal of the veils separating man from God as given to man by God himself. This is kashf.[10]
The 18th century mystic Khwaja Mir Dard (died 1785) (relying upon the traditional terminology, classified the revelations as follows in his `Ilm al-Kitab:
