Shaykh al-Islām—may Allah sanctify his soul—was asked:
“What do the leading scholars of Islam say about al-Hallāj? What ruling applies to someone who says, ‘I believe what al-Hallāj believed,’ and says, ‘He was killed unjustly, just as some of the prophets were killed,’ and says, ‘Al-Hallāj is one of Allah’s righteous friends’? What ruling applies to him for saying this, and was al-Hallāj executed in accordance with the Sharia?”
He answered:
Praise be to Allah. Whoever holds the beliefs for which al-Hallāj was executed is a disbeliever and an apostate, by the unanimous agreement of the Muslims. The Muslims executed him for his doctrines of divine indwelling and union with God, and similar teachings of those given to heresy and unbelief, such as his saying, “I am Allah,” and his saying, “A god in heaven and a god on earth.”
It is necessarily known in the religion of Islam that there is no deity worthy of worship except Allah, that Allah is the Creator of all things, and that everything besides Him is created, and:
“There is no one in the heavens and earth but that he comes to the Most Merciful as a servant.”
He said, Most High:
“O People of the Scripture, do not commit excess in your religion or say about Allah except the truth,”
and the subsequent verses. He also said, Most High:
“They have certainly disbelieved who say, ‘Allah is the Messiah, the son of Mary,’”
and the following verse. Thus the Christians whom Allah and His Messenger declared to be disbelievers, and whom the Muslims unanimously regard as disbelieving in Allah
