Yaqeen is generally translated as "certainty", and is considered the summit of the many stations by which the path of walaya is fully completed. This is the repository of liberating experience in Islam. In relation to the exotericreligious life, certainty is the sister of religious life in its perfection, that is, to say the adoration of Allah according to the visionary way; through this channel it is the pillar of Islam in the accomplishment of its externalpractices, as it is the foundation of faith in its internal dogma. It is, in fact, ihsân which gives the external religion its true meaning and the domain of faith its real values. It occurs in the Quran about certainty, "And worship your Lord until there comes to you the certainty". Certainty comprises three degrees.
Stages
Ilm-ul-yaqeen (the knowledge of certainty)
The first degree is referred to by the name ‘ilm-ul-yaqeen, which means that certainty is the result of knowledge. At this degree the object of certainty is knowledge just as the aim of knowledge is certainty. Both together are in the soul uniquely, such that certainty is the first degree of spiritual life and the last of speculative experience. This particular degree of mysticalyaqeen is the result of divine theophanies in act at the level of existence and also the result of theophanies of lights of nature at the gnosticlevel.
Ayn-ul-yaqeen (the vision of certainty)
The second degree of yaqeen is what one calls in Sufi terms ayn-ul-yaqeen, that is, certainty as a consequence of contemplation and vision. At this level, the object of certainty is present in front of the gnostic and is not only a speculative concept. Here knowledge becomes what one calls 'ilm-e-huzuri’’, and that is the second aspect of Certainty in the spiritual way and in liberating experience. By this kind of knowledge, the man of the Way is distinguished from philosophers and learned men. This particular degree of spiritual Certainty is the result of divine theophanies of Attributes at the level of existence.
Haqq-ul-yaqeen (the final level of certainty gained through experience)
Finally, the last degree of yaqeen is called haqq-ul-yaqeen, that is, certainty as supreme truth. Here, certainty has a particular coloring: it is the fruit of an all-embracing experience because the object of certainty is identical to the one who is experiencing it, knowledge being transformed into actual experience and actual experience into knowledge. At this stage, in fact, knowledge is not limited to the intellect, nor to the vision of the one who is contemplating it, it becomes one with the human being. This is the final phase of yaqeen, the apotheosis of the spiritual and intellectual journey. This high degree of Sufi certainty is the effect of the Emanation of the divine Theophanies in Essence at its existential level and that of the diffusion of the Light of lights at the level of the theophanies of the gnostic.
