Al-Hallaj

The 'drunken Sufis' exemplified by Bistami (Armstrong 1993: 261) desired to become one with the beloved in anihilation ('fana): "I gazed upon al-Lah with the eye of truth and said to Him: 'Who is this?" He said "This is neither I nor other than I There is no God but I" Then he changed my out of my identity into his Selfhood. Then I communed with him with the tongue of his face, saying "How fares it with me with Thee? He said "I am through Thee, there is no God but Thou".

This was taken to its visionary conclusion by al-Hallaj, the 'wool carder'

I am He whom I love, and He whom I love is I:
We are two spirits dwelling in one body.
If thou seest me thou seest Him,
And if thou seest Him thou seest us both"
(Armstrong 1993: 263).

However when he preached overthrow of the Caliphate and cried "ana al-Haqq - I am the truth" as Jesus did, he was crucified.

"When he saw the cross of nails he turned and uttered a prayer: 'And these Thy servants who are gathered to slay me, in zeal for Thy religion and in desire to win Thy favours, forgive them O Lord, and have mercy upon them; for verily if Thou hadst revealed to them what thou hast revealed to me, they would not have done what they have done,; and if Thou hadst hidden from me what you have hidden from them, I should not have suffered this tribulation. Glory unto Thee in whatsoever thou doest, and glory unto Thee in whatsoever Thou willest' "

~ from The Tao of the Sufi

So, there has been more than one Anointed who has suffered death for his extreme love of the Divine.

The Beloved

One went to the door of the Beloved and knocked.
A voice asked: 'Who is there?' He answered: 'It is I.'
The voice said: 'There is no room here for me and thee.'
The door was shut.

After a year of solitude and deprivation
this man returned to the door of the Beloved.
He knocked.
A voice from within asked: 'Who is there?'
The man said: 'It is Thou.'
The door was opened for him.
