Different Muslims, both Sunnis and Shi'is, have varying views about al-Hallaj. Some take a negative view of him, especially this statement, and others appreciate the spirit of it.
Regarding al-Hallaj, Ayatollah Motahhari says in his introduction to 'irfan:

Now famous simply as al-Hallaj, he is one of the most controversial mystics of the Islamic world. The shathiyyat uttered by him are many, and he was accused of apostasy and claiming divinity. The jurisprudents pronounced him an apostate and he was crucified during the reign of the 'Abbasid caliph al-Muqtadir.
The 'urafa' themselves accuse him of disclosing spiritual secrets. Hafiz has this to say about him:
He said, that friend, who was raised high on the cross,
His crime was that he used to reveal secrets.
Some consider him no more than a charlatan, but the 'urafa' themselves absolve him and say that the statements of al-Hallaj and Bayazid that gave the impression of unbelief were made when they were beside themselves in the state of 'intoxication'.
Al-Hallaj is remembered by the 'urafa' as a martyr. He was executed in 309/913.
