Do we have to say bismillah when reading surah at tawbah from the middle? Also why is there no bismillah in the begining of surah tawbah?

Question

Praise be to Allah.

Firstly:

Part of the etiquette of reciting Qur’aan is for the reciter to
always say Bismillah ir-Rahmaan
ir-Raheem (In the name of Allah, the Most Gracious,
the Most Merciful) at the beginning of every soorah,
except Soorat at-Tawbah.

Imam an-Nawawi
(may Allah have mercy on him) said: He should always recite Bismillah
ir-Rahmaan ir-Raheem at the
beginning of every soorah except Soorat
Baraa’ah (at-Tawbah),
because the majority of scholars said that it is a verse wherever it is written
in the Mushaf, and it was written at the beginning of
all the soorahs except Soorat
at-Tawbah. If he recites it at the beginning of every
soorah (other than at-Tawbah),
then there is certainty that he had recited the entire Qur’aan
or soorah, and if he fails to recite the Basmalah, he has omitted part of the Qur’aan
according to the majority.

But if he recites from partway through a
soorah, he does not have to recite the Basmalah and it is sufficient for him to seek refuge with
Allah (by saying A‘oodhu Billaahi min ash-Shaytaan ir-rijeem (I seek refuge with Allah from the accursed Shaytaan), but if he does say the Basmalah
there is nothing wrong with that. For more information please see the answer to
question no. 21722

Secondly:

The reason why the Basmalah
does not appear at the beginning of Soorat at-Tawbah is that the Sahaabah (may
Allah be pleased with them) did not write it at the beginning of this soorah in the Mushaf, following
the example of the caliph ‘Uthmaan (may Allah be
pleased with him). At-Tirmidhi narrated in as-Sunan that Ibn ‘Abbaas (may Allah be pleased with him) said: “I said to ‘Uthmaan ibn ‘Affaan:
‘What made you put al-Anfaal which is one of the Mathaani, next to Baraa’ah [al-Tawbah], which is one of the Mi’een?
Why did you not put the line Bismillaah
ir-Rahmaan ir-Raheem in
between them when you put it at the beginning of the rest of al-Sab’ al-Tiwaal [the long seven soorahs]?” ‘Uthmaan said:
“The Messenger of Allaah (peace and blessings of Allaah be upon him) used to receive revelation of soorahs with many aayahs. When
they were revealed, he would call his scribes and tell them, ‘Put these aayahs in the soorah where
such-and-such is mentioned.’ Al-Anfaal was one of the
first soorahs to be revealed in Madeenah,
and Baraa’ah (al-Tawbah)
was one of the last parts of the Qur’aan to be
revealed. Its stories were similar to the stories mentioned in al-Anfaal, so it was thought that it was part of it. The
Messenger of Allaah (peace and blessings of Allaah be upon him) was taken [i.e., died] without
explaining whether it was indeed part of it, so they were put next to one
another, and the line Bismillaahi ir’Rahmaan
ir’Raheem was not written between them, and it [al-Tawbah] was put among the Sab’
al-Tiwaal [seven long soorahs].”

Shaykh Ibn ‘Uthaymeen (may Allah have
mercy on him) said: … The correct opinion is that there is no Basmalah between it (Soorat at-Tawbah) and al-Anfaal, because
the Basmalah is a verse of the Book of Allah, may He
be glorified and exalted, and if the Messenger (blessings and peace of Allah be
upon him) did not say to put the Basmalah between the
two soorahs, they did not put it between them. The
Prophet (blessings and peace of Allah be upon him) is the one who decided and
said: Put the Basmalah, and he did not tell them to
put the Basmalah between Soorat
al-Anfaal and Soorat at-Tawbah, so they did not write it. But it remains to be
said: if he did not give instructions to this effect, why is there a separation
between it and Soorat al-Anfaal?
Why did they not make it one soorah? We say: Yes,
they did not make it one soorah because they were
uncertain as to whether it was the same soorah as al-Anfaal or they were two separate soorahs,
so they said: Let us make a separation between the two soorahs
and not write the Basmalah. This is the correct
opinion concerning the absence of the Basmalah
between Soorat al-Anfaal
and Soorat at-Tawbah.
