Raising the voice when saying Tasbeeh on Friday

Is saying Tasbeeh in a loud voice on Friday for an hour or more before
Jumu'ah prayers Sunnah or bid'ah?
Praise be to Allaah.
Undoubtedly this action is bid'ah, because it has not been transmitted
to us that the Prophet (peace and blessings of Allaah be upon him) or
his companions did that,and all goodness is to befound in following
them.But if a person says Tasbeeh to himself, there is nothing wrong
with that, indeed it brings much good and a great reward, because it
was narrated in a saheeh report that the Prophet (peace and blessings
of Allaah be upon him) said: "The most beloved of words to Allaah are
four: Subhaan Allaah (Glory beto Allaah), al-hamdu Lillaah (praise be
to Allaah). Laa ilaaha ill-Allaah (there is no godexcept Allaah) and
Allaahu akbar (Allaah is Most Great)." (Narrated by Muslim, al-Adaab,
2137)
And he (peace and blessings of Allaah be upon him) said: "Two words
which are light on the tongue but whichare dear to the Most Merciful
and will weigh heavily in the balance: Subhaan Allaah wa bi hamdih,
subhaan Allaah il-'Azeem (Glory and praise be to Allaah; Glorybe to
Allaah the Almighty)." (Narrated by al-Bukhaari, al-Aymaan
wa'l-Nudhoor, 6682; Muslim, al-Dhikr wa'l-Du'a' wa'l-Tawbah
(Remembering Allaah, supplication and repentance, 2694).
