fear of death drives religion, page-137

RM, “Hades,” is the Greek counterpart of the Hebrew word “Sheol.” It is not an equivalent of "abyss". On the day of Pentecost 33 C.E., the apostle Peter referred to David’s death and quoted Psalm 16:10: “You will not leave my soul in Sheol.” After mentioning that David was still in his tomb, Peter applied those words to Jesus and indicated that David “saw beforehand and spoke concerning the resurrection of the Christ, that neither was he forsaken in Hades nor did his flesh see corruption. This Jesus God resurrected, of which fact we are all witnesses.” (Acts 2:29-32)
Thus, those said to be in Hades are in the same situation as those said to be in Sheol. They are sleeping, awaiting a resurrection. Satan is never spoken of as being in " hades " or "sheol " as it is the common grave of mankind.
