Sufism (Islamic mysticism) features different grades and levels based on how able a Muslim mystic is to reach Allah.
One of these levels is called ‘Al Arif Billah’ (Knower of Allah). However, knowledge here refers to the supreme mystic knowledge, which is “Knowledge of Allah.”
Sufism, unlike other Islamic modality, emphasizes self-purification and the attainment of spiritually advanced states. Thus, spirituality became Sufism’s main gauge.
Knowledge in Sufism is firmly focused on knowing al-haqiqa (Reality), which indicates the essential reality of things or the divine truth, and Basirah (Inner eye), which perceives the world of the unseen.
Haqiqa and Basirah in Sufism are mainly related to Ilham (Inspiration) and Kashf (Unveiling), which are believed to be gifted by Allah to His slave and sincere worshipers as a Divine Self-disclosure.
In order for a Muslim mystic to reach the ‘Knower of Allah” level, he must attain certain devoted levels of dedication and worshiping.
Some Sufis, on the other hand, took advantage of the vague understanding of the ‘Knower of Allah’ level as they claimed reaching it, putting them under fire by other religious modalities.
Sufi order Tijaniyyah scholar Sheikh Ahsan al-Baqili affirms that reaching the ‘knower of Allah’ level requires a far superior state.
Sufi scholar-saint Sheikh Ibn Arabi claimed that all of his writings are through revelation, “despite of not being messengers or prophets.”
It is believed in Sufism that close worshippers might become ahl al-kashf wa’l-wujud (People of unveiling and finding), or the knowers, who have passed beyond the veils which stand between themselves and their God.
These people are granted sirr al-haqiqah, which is that which is beyond verbal expression. It can merely be hinted at through subtle allusion or indications.
