At-Tawbah (Arabic: ٱلتوبة‎, at-Tawbah; meaning: The Repentance), also known as Bara'ah (Arabic: براءة‎, Barāʾah; meaning: Repudiation), is the ninth chapter (sūrah) of the Quran. It contains 129 verses (āyāt) and is one of the last Medinan surah.

This Surah is reported to have been revealed at the time of the Battle of Tabuk in Madinah in the 9th year of the Hijrah. The Sanaa manuscript preserves some verses, on parchment radiocarbon dated to between 578/44bh and 669/49ah.

It is the only Surah of the Quran that does not begin with Bismillah, the usual opening formula, In the name of Allah, the All-Merciful, the All-Compassionate. It deals with almost the same topics as those dealt with in Surat al-Anfal. In contrast to all other surahs, Muhammad did not order that this formula should be put at the beginning of this surah.
