The Fusus al-Hikam is one of the most precious short writings of our Shaykh... One of the last and most complete book sent down upon him, it came to him from the station of Muhammad, the Fountain head of the Essence, and the unitary All-Comprehensiveness. So it contains the epitome of the spiritual perception (dhawq) of our Prophet - God's blessings be upon him - concerning the Knowledge of Allah. It also points to the source of the spiritual perceptions of the prophets mentioned within it. It leads every man of spiritual insight to the gist of their spiritual perceptions, the objects of their intentions and aspirations, the sum of all they achieved, and the outcome of their perfections. So it is like the seal of everything comprised with in the perfections of each of them; it gives news of the source of what they encompassed and what the made manifest. Shaykh Saddruddin al-Qunawi in al-Fukuk
