Abrahams's son never died, not a hair of his head was harmed. Ergo, the 3-day theory for whatever you were trying to purvey was not even close to an exegesis of that event.
The OP never suggested that Abraham's son died [that is, literally].
Personally, I believe the OP is referencing the following passage:
Hebrews 11:17-19 -
"
17 By faith Abraham, being tested, has offered up Isaac. Even the
one having received the promises was offering up
his only begotten son,
18 as to whom it was said, “In Isaac your offspring will be reckoned,”
b 19 having reasoned that God was able even to raise him out from the dead,
from where he received him also in a simile [/parable - G3850]."
So, it would have been when Abraham "set out" to this task, that he already considered his son as an offering ['dead'], where we read
in Genesis 22 -
"2 And he said,
Take now thy son, thine only son Isaac, whom thou lovest, and
get thee into the land of Moriah; and offer him there for a burnt offering upon one of the mountains
which I will tell thee of.
3 And
Abraham rose up early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son,
and clave the wood for the burnt offering, and rose up,
and went unto the place of which God had told him.
4 Then
on the third day Abraham lifted up his eyes, and saw the place afar off.
