TT #18 · Parashas Chayei Sarah · Passuk 24:1
Avraham was now old, advanced in years, and Hashem had blessed Avraham in all things.
Torah Temimah points to Bava Basra 17a. E-Daf · Sefaria — Bava Basra 17a
TT lemma: בכל.
Our Rabbis taught: The Holy One let Avraham our father taste of the World to Come while still in this world, and the evil inclination, the Angel of Death, and the worm did not rule over him, as it is written “And Hashem blessed Avraham in all.”
Custom (Bavli — Avraham’s portion of the World to Come in this life)
Avraham was granted a foretaste of the World to Come already in this world; the evil inclination, the Angel of Death, and post-mortem decay had no power over him, fulfilling the blessing “in all.”
