Unrestricted Takbeer or Takbeer restricted to certain times during the days of Dhu’l-Hijjah

About unrestricted Takbeer during Eid al-Adha – is the Takbeer
following every prayer included in the unrestricted Takbeer? Is it
Sunnah, mustahabb orbid'ah?
Praise be to Allaah.
With regard to Takbeer on (Eid al-) Adhaa, it is prescribed from the
beginning of the month until the end of the thirteenth day of
Dhu'l-Hijjah, because Allaah says (interpretation of the meaning):
"That they may witness things that are of benefit to them (i.e. reward
of Hajj in the Hereafter, and also someworldly gain from trade), and
mention the Name of Allaah on appointed days"
[al-Hajj 22:28]
- which are the ten days;and because Allaah says (interpretation of
the meaning):
"And remember Allaah during the appointed Days [These are the three
days of staying at Mina during the Hajj; 11th, 12th and 13th daysof
the month of Dhul-Hijjah]" [al-Baqarah 2:203]
- which are the days of Tashreeq.
And the Prophet (peace and blessings of Allaah be upon him) said: "The
days of Tashreeq are the days of eating, drinking and remembering
Allaah." (Narrated by Muslim in his Saheeh). Al-Bukhaari mentioned in
his Saheeh, in a mu'allaq report, that Ibn 'Umar and Abu Hurayrah (may
Allaah be pleased with them both) used to go out to the market-place
on first ten days of Dhu'l-Hijjah, reciting Takbeer, and the people
used to recite Takbeer because of their Takbeer. 'Umar ibn al-Khattaab
and his son 'Abd-Allaah (may Allaah be pleased with them both) used to
recite Takbeer during the days of Mina in the mosque and in the camps,
and they would raise their voices until Mina echoedwith their Takbeer.
It was narrated that the Prophet (peace and blessings of Allaah be
upon him) and a group of the Sahaabah (may Allaah be pleased with
them) used to recite Takbeer following each of the five prayers from
Fajr on the day of 'Arafaah until 'Asr on thethirteenth day of
Dhu'l-Hijjah. This applies to those who are not on Hajj; for those who
are on Hajj, they should concentrate on their ihraam and recite the
Talbiyah, until they throw the stones at Jamarat al-'Aqabah on the Day
of Sacrifice (Yawm al-Nahr); after that they may recite Takbeer. The
Takbeer should start with the first stone thrown at the Jamarah
mentioned. If the pilgrim recites the Takbeer along with the Talbiyah,
that is OK, because Anas (may Allaah be pleased with him) said: "Some
would recite the Talbiyah on the Day of 'Arafaah, and they were not
told off for doing so, and some would recite Takbeer and they were not
told off for doing so." (Narrated by al-Bukhaari). But it is better
for the one who isin ihraam to recite the Talbiyah and for the onewho
is not in ihraam to recite Takbeer on the days mentioned.
Hence we know that according to the most correct scholarly view,
unrestricted takbeer andtakbeer restricted to certain times are
combined on five days, i.e., the Day of 'Arafaah, the Day of Sacrifice
and the three days of Tashreeq. With regard tothe eighth day (of
Dhu'l-Hijjah) and the days preceding it, Takbeer onthose days may be
done at any times, not only at certain times, because ofthe aayahs and
reports mentioned above. In al-Musnad it is narrated from Ibn 'Umar
(may Allaah be pleased with him) that the Prophet (peace and blessings
of Allaah be upon him) said: "There are no days on which good deeds
are greater or more beloved to Allaah than on these ten days, so
recite much Tahleel (saying Laa ilaaha ill-Allaah), Takbeer (saying
Allaahu akbar) and Tahmeed (saying al-hamdu Lillaah)," or similar
words.
