Thus, the Holy Spirit is not something that belongs exclusively to the Messiah—peace be upon him. Everything that is explained by the title “the Son” or by the term “the Holy Spirit,” and every other description applied to the Messiah, is in fact shared between him and the other messengers. If people interpret hulūl (indwelling) to mean the appearance of Allah’s light, knowledge, and guidance in His prophets, then that is true, and it is common to the Messiah and to others.
As for the very Essence of Allah, it has never indwelt any human being.
Muslims, while bearing witness that the Messiah is the servant and messenger of Allah, also affirm that he is divinely supported and protected: Allah safeguarded him from his enemies, purified him of their harm, and never allowed them to gain power over him.
Christians, by contrast, claim that the name “Messiah” unites both lāhūt (divinity) and nāsūt (humanity), and that he is fully God and fully man—something that revelation and sound reason alike declare impossible. Yet they go on to attribute to him mutually contradictory qualities: they say that a band of wicked Jews placed a crown of thorns on his head, spat in his face, humiliated him, crucified him, and treated him in a way unbefitting even the lowest of men, while at the same time asserting that he is the Lord of the heavens, the earth, and all that lies between them.
