If the people around him are reciting the Talbiyah in unison, should he remain silent?

My question is about reciting the Talbiyah in unison. I have read your
fatwa and the commentsof Shaykh Ibn 'Uthaymeen (may Allah have mercy
on him). I would like to know: What should a person doif he is on the
bus and it is difficult for them to recite the Talbiyah individually,
and even if they start to do that, they end up reciting it together.
The Sahaabah (may Allah be pleased with them) did not travel
altogether in the same group; they may have been far from one another.
So do the pilgrims have a reason for doing that, i.e., reciting the
Talbiyah in unison? Especially because of the fitnah that may result
for the one who acts differently from the people, most ofwhom think it
is permissible to do that. I also want to ask: is it better for a
person to remain silent because hecannot help reciting with them
otherwise, or should he recite it with them? May Allah bless you for
explaining this important matter.
Praise be to Allaah.
Reciting the Talbiyah in unison was not related from the Prophet
(blessings and peace of Allah be upon him) or from his Companions.
Hence a number of scholars stated that this is an innovation (bid'ah).
It says in Fataawa al-Lajnah ad-Daa'imah (11/358): What is the ruling
on pilgrims reciting the Talbiyah together, whereby one person says it
and the others follow?
Answer: It is not permissible to do that because it was not narrated
from the Prophet (blessings and peace of Allah be upon him) or from
the Rightly Guided Caliphs who succeeded him (may Allah be pleased
with them). Rather it is an innovation. End quote.
This applies to those who deliberately recite the Talbiyah in unison.
As for the one who is reciting the Talbiyah with other people nearby,
and their voices coincide unintentionally,there is no blame on him.
What usually happens when people are together, reciting the Tabliyah
out loud, is thattheir voices will coincidesometimes. If the people
around you are reciting the Talbiyah in unison, you should not keep
quiet; rather you should recite the Talbiyah out loud too.
If you are afraid that thismay result in negative consequences, if the
people around you notice that you are reciting the Talbiyah on your
own, then recite in a quiet voice, But remaining silent is not
appropriate, because the Talbiyah is a righteous deed and a beneficial
act of worship.
An-Nasaa'i (2753), at-Tirmidhi (829), Abu Dawood (1814) and Ibn Maajah
(2923) narrated from as-Saa'ib ibn Khallaad that the Messenger of
Allah (blessings and peace of Allah be upon him) said: "Jibreel came
to me and said: 'O Muhammad! Tell your companions to raise their
voices when reciting the Talbiyah.'" Classed as saheeh by al-Albaani
in Saheeh an-Nasaa'i.
A version narrated by Ibn Maajah says: "Let them raise their voices
when reciting the Talbiyah, for it is one of the symbols of Hajj."
At-Tirmidhi (827) and Ibn Maajah (2896) narrated from Abu Bakr
as-Siddeeq that the Prophet (blessings and peace of Allah be upon him)
was asked: Which (actions of) Hajj are best? He said: "Raising the
voice in Talbiyah andslaughtering the sacrificial animal."
Classed as saheeh by al-Albaani in Saheeh at-Tirmidhi.
And Allah knows best.
