named with Him" is the term for the Resurrection. So according to this, the meaning is: He decreed an appointed term, and He informed you that you remain until death, but He did not inform you of the term of the Resurrection.
1263: 7105: Himself: 1: Ibn Kathir said: The exegetes of this verse differed in their interpretations after they reached a consensus on rejecting the early Jahmiyyah who said—exalted is He far above what they say—that He is in every place, as they interpreted the verse in that way.

There would have entered into them such terror from his speech and caution towards him that would prevent them from speaking to him and prohibit them from asking him questions; thus, the benefit would not be universal. If He had transformed him from the form of angels to something similar to their own form so that they might be comforted by him
