Which case, and why?

From the water of Maryam, or from the blowing of Jibrīn [Gabriel] in the form of the mortal (bashar) existent from clay, the spirit came to be in an essence purified of nature, [nature] which you call Sijjīn. Because of that, his sojourn in it [i.e., in the world] was prolonged, so that it exceeded a thousand [years] by specification. A spirit from God, not from other than Him; therefore he gave life to the dead and brought the bird into being from clay, so that a lineage from his Lord might be valid for him, by which he exerts effect upon the high and the low. God purified him in body, made him incomparable in spirit, and made him a likeness [of Himself] in engendering. Know that among the special properties of spirits is that they do not tread upon anything without that thing coming to life and life permeating it.
