Should he send blessings on the angels in the tashahhud?

Is it permissible to send blessings on the angels in the tashahhud as
I send blessings on the Prophet (peace and blessings of Allaah be upon
him)?.
Praise be to Allaah.
In the answer to question no. 105330 we stated thatit is prescribed to
send blessings on the angels.
But in the tashahhud doing that is not prescribed, because what must
be done is to recite only that which was proven from the Prophet
(peace and blessings of Allaah be upon him), without adding anything
to it.
Shaykh Saalih al-Fawzaan was asked: Should blessings be sent on the
angels in the tashahhud as they are sent on the Prophet (peace and
blessings of Allaah be upon him)?
He replied:
No, the blessings that are mentioned in the tashahhud should be
limited only to that whichis narrated, but when we say al-salaamu
'alayna wa'ala 'ibaad-Allaah al-saaliheen (may peace be upon us and
upon all the righteous slaves of Allaah), that includes every
righteous slave in heaven and on earth, which includes the angels.
