Surah 'At-Tawbah' and 'Bismillah'

Q633 :Why does surah 9 not start with the normal beginning which translates as "In the name of Allah, the Merciful, the Beneficent".

A633 : Surah 9 entitled 'At-Tawbah' or 'repentance', exposes the true qualities of the hypocrites and threatens them with a woeful doom. It can be likened to a stern warning made in the strongest terms. Hence, an opening which stresses divine mercy and compassion does not seem particularly fitting to the subject matter of the surah. Therefore, Allah has not started with the phrase you have mentioned which begins every other surah in the Qur'an. To recite this phrase at its beginning is forbidden because it constitutes an addition to the Qur'an which is not part of it.
