[Avodah] Moshe Rabeinu's stuttering

[Danny Schoemann]

My 8 year old wanted to know why Moshe Rabeinu's stuttering wasn't
healed at the burning bush.

To this I answered that since Moshe Rabeinu didn't daven for it, it
didn't happen. (Great opportunity for a little lesson in the power of
davening.)

She then claimed that Moshe Rabeinu's stuttering was healed at Matan
Torah, since all ailments were then cured. Do we have a reliable
record to prove/disprove that Moshe Rabeinu was included/excluded from
that?
