Yaqeen

Yaqeen () is generally translated as "certainty", and is considered the summit of the many stations by which the path of ''walaya'' (sometimes translated as Sainthood) is fully completed. This is the repository of liberating experience in Islam. In relation to the exoteric religious life, certainty is the sister of religious life in its perfection (''ehsân''), 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 external practices, as it is the foundation of faith (''iman'') 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 (''yaqeen'') comprises three degrees. Provided by Wikipedia
