At-Tawbah in the context of "Āyah"

A surah (/ˈsʊərə/; Arabic: سُورَة, romanized: sūrah; pl. سُوَر, suwar) is an Arabic word meaning "chapter" in the Quran. There are 114 surah in the Quran, each divided into verses (Arabic: آيات, romanized: āyāt, lit. 'signs'). The surah are of unequal length; the shortest surah ("al-Kawthar") has only three verses, while the longest (al-Baqarah) contains 286 verses. The Quran consists of one short introductory chapter (Q1), eight very long chapters, making up one-third of the Quran (Q2‒9); 19 mid-length chapters, making up another one-third (Q10‒28); and 86 short and very short ones of the last one-third (Q29‒114).

Of the 114 surah in the Quran, 86 are classified as Meccan (Arabic: مكي, romanized: makkī), as according to Islamic tradition they were revealed before Muhammad's migration to Medina (hijrah), while 28 are Medinan (Arabic: مدني, romanized: madanī), as they were revealed after. This classification is only approximate in regard to the location of revelation; any surah revealed after the migration is termed Medinan and any revealed before it is termed Meccan, regardless of where the surah was revealed. However, some Meccan surah contain Medinan verses (verses revealed after the migration) and vice versa. Whether a surah is Medinan or Meccan depends on if the beginning of the surah was revealed before or after the migration.

The Quran is divided into 114 chapters, called surahs (Arabic: سُورَة, romanized: sūrah; pl. سُوَر, suwar) and around 6,200 verses (depending on school of counting) called ayahs (Arabic: آية, Arabic pronunciation: [ʔaː.ja]; plural: آيات ʾāyāt). Chapters are arranged broadly in descending order of length. For a preliminary discussion about the chronological order of chapters, see Surah.

Each surah except the ninth (al-Tawba) is preceded by a formula known as the basmala or tasmiah, which reads bismi-llāhi r-raḥmāni r-raḥīm ("In the name of Allah, the Most Gracious, the Most Merciful."). In twenty-nine surahs, this is followed by a group of letters called "muqaṭṭa'āt" (lit. "abbreviated" or "shortened"), unique combinations of a few letters whose meaning are unknown.

The Basmala or Basmalah (Arabic: بَسْمَلَة, romanized: basmalah; also known as Tasmiya by its opening words Bi-'sm-illāh; بِسْمِ ٱللهِ, "In the name of God") is an Islamic phrase meaning “In the name of God, the Most Gracious, the Most Merciful” (Arabic: بِسْمِ ٱللهِ ٱلرَّحْمَٰنِ ٱلرَّحِيْمِ, bi-smi llāhi r-raḥmāni r-raḥīm). It is one of the most important phrases in Islam and is frequently recited by Muslims before performing daily activities and religious practices, including prayer, and at the start of verses (āyah) or chapters (surahs) of the Qur'an.

In the Quran, it is recited before each chapter (surah), except for the ninth chapter At-Tawbah. Scholarly debates regarding its inclusion in the Qur'anic text reached consensus with the 1924 Cairo Edition, where it was included as the first verse (āyah) of Al-Fatiha and remained an unnumbered line preceding each of the 112 other chapters.
