Dought & clear, - Reciting the Basmalah in the prayer.

Must he say "Bismillahi rahman nirahim" quietly after finishing
al-fatihah in order to begin the sura he will recite? What if he
begins reciting in the middle of a sura?.
Praise be to Allaah.
Reciting the Basmalah (i.e., the phrase "Bismillaah ir-Rahmaan
ir-Raheem(in the name of Allaah, the most Gracious, the Most
Merciful)" is mustahabb (encouraged), not obligatory. It is mustahabb
if you are going to recite a soorah from the beginning, so the
worshipper says it before al-Faatihah. With regard to the soorah after
al-Faatihah, if he is reciting it from the beginning of the soorah,
then he should say the Basmalah, apart from Soorat al-Tawbah, because
the Basmalah is not recited at the beginning of it. If he is reciting
from the middle of a soorah, then it is not mustahabb to recite the
Basmalah.
The Standing Committee said:
The sound Sunnah indicates that the Prophet(peace and blessings of
Allaah be upon him) recited the Basmalah in prayer before al-Faatihah
and before other soorahs, apart from Soorat al-Tawbah, but he did not
recite it out loud in the prayers in which he recited Qur'aan out
loud.
Fataawa al-Lajnah al-Daa'imah, 6/378
They also said:
It is prescribed to recite the Basmalah in every rak'ah before
al-Faatihah and before every soorah apart from Soorat Baraa'ah (i.e.,
Soorat al-Tawbah).
Ibid.
And they said:
If (the worshipper) is going to recite a soorah after al-Faatihah, he
should recite the Basmalah silently beforehand. But if he is going to
recite a brief passage from the middle or end of a soorah, then it is
not prescribed for him to recite the Basmalah.

And Allaah knows best.
