(Ayan al Thabita). The immutable entities or fixed prototypes or established essences or potentialities. These are the infinite and immutable Possibilities which are fixed in the Ipseity. The fixed entities are the images of the Divine Names and Qualities and 'things' of the Ipseity in the Presence of Knowledge, with specific individuation. The term signifies the essential character of every individual existing from eternity in the Divine Knowledge. They are established according to non-existence and they are not qualified by existence.
(Idhn). Permission of one in authority. It is always the higher authority that gives permission to that which is lower. Therefore within the Spiritual Path this permission always comes from The Highest Authority - Allah. Permission (idhn) for the murid to undertake spiritual practices is given by his Murshid. In reality this permission descends from Allah Almighty through His Holy Prophet Muhammad (May the Salutations of Allah be upon him and Peace) and then into the hearts of the Noble Mashayekh of the Spiritual Paths. It is this Supreme Permission that permeates the spiritual practices and infuses them with their powerful barakah.
(Kibrit Ahmar). This term is used to indicate a highly personal spiritual realization or a vision of great rarity. The Red Sulphur is the sought-after and rare working principle which turns base metal into gold. Finding one's Spiritual Guide/Murshid is often referred to as 'finding the red sulphur'. Finding the hidden treasure within one's own secret is the Red Sulphur. Finding the Red Sulphur is rare, yet some of the great friends of Allah have found it in abundance! The universal meaning of Sulphur is the Divine Command.
