Occasions or circumstances of revelation, in Arabic( أسباب النزول -asbāb al-nuzūl,) names the historical context in which Quranic verses were revealed from the perspective of traditional Islam. Though of some use in reconstructing the Qur'an's historicity, asbāb is by nature an exegetical rather than a historiographical genre, and as such usually associates the verses it explicates with general situations rather than specific events. The study of asbāb al-nuzūl is part of the study of Tafsir (interpretation of the Qur'an).

Asbāb أَسْبَابْ is the plural of the Arabic word sabab سَبَبْ, which means "cause", "reason", or "occasion", and nuzūl نُزُولْ is the verbal noun of the verb root nzl ن ز ل, literally meaning "to descend" or "to send down", and thus (metaphorically) "to reveal", referring God (Allah) sending down a revelation to his prophets.

The reasons for revelation found in the hadiths are divided into types:

1: The answer that the Prophet Muhammad should give to a question that was asked to him ^[1]

2: Comment on events that occurred.^[2]

3: The first type is the category of people, as there are verses that only speak to non-mulims and some verses only speak to mulims.^[3]

Modern scholarship has long posited an origin for the sabab al-nuzūl based largely on its function within exegesis. William Montgomery Watt, for example, stressed the narratological significance of these types of reports: "The Quranic allusions had to be elaborated into complete stories and the background filled in if the main ideas were to be impressed on the minds of simple men."^[4] John Wansbrough, on the other hand, noted their juridical function, particularly with regard to establishing a chronology of revelation for the purposes of such mechanisms as naskh.^[5] Rippin in turn rejected this, arguing that the sabab's primary function is in haggadic/qissaic exegesis, and that this in turn hints at its origin:

The primary (i.e., predominant) function of the sabab in the exegetical texts is not halakhic [juridical] ... the essential role of the material is in haggadic exegesis... I would tentatively trace the origins of this material to the context of the qussās, the wandering story-tellers, and pious preachers and to a basically popular religious worship situation where such stories would prove both enjoyable and edifying.^[5]

One thing common to all these theories is the assumption that the sabab is built around the Qur'ānic verse(s) embedded in it. In his extensive survey of early Muslim traditions regarding Muhammad, Rubin upends this consensus (while preserving Rippin's speculation about the ultimately qassaic/story-teller origins of these reports) by arguing that most asbāb originally started as prophetic biographical material into which Qur'anic verses were only later inserted:

To begin with, one should bear in mind that although the traditions known as asbāb al-nuzūl occur in the collections of tafsīr- for example, al-Tabarī's- their birthplace is in the sīra, where they do not yet function as asbāb. These traditions only became asbāb when the Quran exegetes gleaned them from the sīra and recorded them in the tafsīr of the Quran. Within the realm of the sīra, these traditions are still without an exegetic function, because none of them is built around the Quranic verses which occur in it... The basic narrative framework is always independent of Quranic verses and ideas; the Quranic data seem to have been incorporated into the sīra story secondarily, for the sake of embellishment and authorization. In other words, no process of spinning a narrative around a Quranic verse seems to have taken place...

Quranic materials only began to be applied to the non-Quranic basic narrative framework when the sacred scripture became a standard source of guidance. At this stage, the quṣṣāṣ (story-tellers) could promote the Islamic status of their traditions (originally suspect of biblical influence) by extending to them the divine authority of the Quran. This was achieved by dragging various passages from the scriptures into the narrative. The same Quranic extract could actually be installed in different scenes of Muhammad's life...

Some of the asbāb, but not necessarily all of them, were later gleaned from the sīra and later incorporated into the specialized tafsīr and asbāb al-nuzūl compilations.^[6]

Rubin bases that conclusion partly upon the very stereotyped way in which "linking words" are used to introduce Qur'anic verse into a report.^[7] Mostly, though, he relies upon the existence of multiple parallel non-Qur'anic forms of the narrative for most asbāb. By assuming that a report's link to scripture would not be removed once established, the non-Qur'anic (and thus non-exegetic) version of the report is in fact the original one. Rippin takes issue with this last assumption, though, by arguing that the evidence does not preclude the creation of parallel sīra narratives even after the circulation of a supposedly "authoritative" Qur'anic one.^[8]

The Quran was revealed over a period of nearly twenty three years. Muslim scholars agree that the revelations of the Quran can be divided into two broad types: One type includes passages of the Quran which were revealed in response to specific events, incidents or questions put forward to Muhammad. The second type includes passages of the Quran which were not direct responses to any historical or social development in the life of the Muslim community. A thorough understanding of the first type of passages, therefore, depend on knowing the circumstances of the events which occasioned them. Such knowledge is an important tool for explaining the meanings of this type of Quranic verses.^[9]

One function of the sabab report is theological. As Rippin notes:

Such reports are cited... out of a general desire to historicize the text of the Qur'ān in order to be able to prove constantly that God really did reveal his book to humanity on earth; the material thereby acts as a witness to God's concern for His creation [ ar-Rahman ]. Indeed al-Suyūtī cites this as one of his understandings of the function of the sabab.^[5]

The occasion of revelation's primary function, though, is exegetical, and by enumerating its various uses within Qur'anic interpretation we visit nearly all the problems of concern for classical Muslim exegetes. These problems span the hermeneutical spectrum, from the most basic units of linguistic meaning to such technical intellectual disciplines as law and philosophy and all points in between. A major underlying difficulty encountered at all levels is the Qur'an's lack of structure. This extends beyond the question of temporal ordering to one of basic unity of thought and expression:

It has often been remarked that the Qur'ān lacks an overall cohesive structure... and does not provide within itself many keys for interpretation. One of the very basic problem is that it is often impossible to tell where one pericope ends and the next one begins.^[5]

The various levels of interpretation along with their typical problems are listed below in order of increasing hermeneutical complexity:

• Lexical: What is the meaning of a particular word?
• Sunnahs in reciting specific verses?
• Intra-Versal/Sentential: Who or what is the referent of a particular pronoun?
• Inter-Versal/Pericopal: What is the relation between verses? Do they constitute a single meaning/unit of thought, or are they distinct?
• Narratological ("Qissaic"): What is the story being told? Why do the characters in it react in the way they do?
• Historical/Ethnological: What events or personages are being described? What cultural practices are being reported and how do they relate the jāhilī scene?
• Legal ("Hukmic"): What are the legal implications of a particular verse and how do these relate to the remaining corpus of Islamic holy law? Is the ruling limited in scope to the circumstances or even unique instant in which it was revealed, or does it define a general principle with broad applicability?

A detailed examination of the function of asbāb at several of these levels follows. Unless otherwise noted examples all come from Rippin's The function of asbāb al-nuzūl in Qur'ānic exegesis (BSOAS 51). Quotations from the Qur'an are taken from the Abdullah Yusuf `Ali translation.

The earliest and the most important work in this genre is undoubtedly Kitab asbab al-Nuzul ("Book of occasions of revelation") by Ali ibn Ahmad al-Wahidi (d. 1075 CE). Al-Wahidi mentions occasions of about 570 verses out of 6236 verses of the Quran. Wahidi's work is not only the first attempt to collect all the material regarding the occasions of revelation in one single volume, but it is also the standard upon which all subsequent works were based. al-Wahidi was born in the city of Nishapur and he died there at an advanced age. He was a poet, philologist, grammarian and Quranic commentator. In fact, He was considered a great commentator of the Quran of his time. His main teacher was the famous Quranic commentator al-Thalabi (d. 1036 CE) and Wahidi seems to have enjoyed the support of the Seljuq vizier Nizam al-Mulk.^[9]

Another important work is by al-Suyuti (d. 1505 CE) which is a slight improvement of al-Wahidi's book. Suyuti wrote his book about four centuries after al-Wahidi. It contains more occasions of revelation compared to Wahidi's work. His work covers 102 chapters (sura) of the Quran while Wahidi's work covers 83 suras. The name of his book is Lubab al-Nuqul fi Asbab al-Nuzul (meaning "The best of narrations concerning the circumstances of revelation").^[16]

No asbāb works from earlier than the 11th century are known, and it is unlikely that this genre of exegetical literature existed before then. Though there is a section titled Nuzūl al-Qur'ān in Ibn al-Nadīm's 10th-century bibliographical catalog Kitāb al-Fihrist (including one Nuzūl al-Qur'ān attributed to the semi-legendary Ibn 'Abbās as transmitted through 'Ikrima), there is no evidence to believe that most of these works ever existed, or that their ambiguous titles signify texts within the asbāb al-nuzūl genre. In Rippin's detailed examination of pre-18th-century exegetical literature,^[16] other works include as follows:

• Asbāb al-nuzūl wa qisas al-furqāniyya by Muhammad ibn As'ad al-'Irāqī (died 1171). Contains sabab reports mixed with qisas al-anbiyā (stories of the prophets) material. The former seem independent of al-Wāhidī's compilation and are isnad-less. Exists in two manuscripts copies, one at the Chester Beatty Library (Manuscript 5199).
• A manuscript (Berlin Staatsbibliothek, Catalog no. 3578). ascribed to al-Ja'barī, probably pseudepigraphicaly. Consists of sabab and naskh material interspersed, with the former containing very abbreviated isnads where only the first authority is listed. According to its final page this manuscript was written in 1309.

Though al-Wāhidī may thus be considered the father of this genre (a view consistent with his rather self-serving depiction of asbāb al-nuzūl as the key to all exegesis), al-Suyūtī made significant contributions to it as well, introducing such refinements as limiting reports to only those contemporaneous with the revelation itself (reports related to events described by the verse were reclassified as akhbār) and developing a sabab selection criterion different from al-Wāhidī's rather mechanistic one of scanning for a select few "marker" introductory phrases.^[16]

Sabab-material did not originate with the asbāb al-nuzūl genre. The chief innovation of the genre was organizational (i.e. the collection of asbāb-material within one text) and to a lesser degree methodological, and so while no work prior to al-Wāhidī's Kitāb may be properly called an instance of asbāb al-nuzūl, material of equivalent function exists in the earliest hadith and tafsir. This distinction will be maintained here by the use of the term sabab-material for an occasion of revelation which does not necessarily come from a work of asbāb al-nuzūl, and sabab only for one that does.

The reasons for asbāb's status as a secondary genre are implicit in this bibliographical overview. Its late emergence (well into the classical period) plus its reliance on earlier tafsir works even for its raw material prevented asbāb al-nuzūl's emergence as a major, independent approach to Qur'anic interpretation.
