of unbelief is manifest knowledge. I counsel you: do not be deluded about Allah, do not despair of Him; do not crave His love, yet never be content with being other than a lover; affirm Him not, nor incline to deny Him; and beware of tawḥid (monotheism). Peace.

It is related from him that he said: “Whoever draws a distinction between faith and unbelief has disbelieved, and whoever fails to distinguish between the believer and the unbeliever has also disbelieved.”

And from him, likewise: “None has affirmed Allah’s oneness except Allah.”

This is the last of what I copied from the handwriting of Shaykh Tāj al-Dīn.
