An introduction to the classical sciences that surround the Quran — its revelation, preservation, structure, and inimitability — as compiled in works like as-Suyuti's al-Itqan and az-Zarkashi's al-Burhan.
هُوَ ٱلَّذِىٓ أَنزَلَ عَلَيْكَ ٱلْكِتَٰبَ مِنْهُ ءَايَٰتٌ مُّحْكَمَٰتٌ هُنَّ أُمُّ ٱلْكِتَٰبِ وَأُخَرُ مُتَشَٰبِهَٰتٌ
Muhkam verses are those whose meaning is clear and decisive — the foundation of the Book. Mutashabih verses are those that admit more than one meaning or whose full reality is known only to Allah (such as the disjointed letters, or the precise nature of the divine attributes). Those firmly grounded in knowledge believe in all of it. The wisdom is to test faith, to drive scholars to deeper study, and to show the need to return the ambiguous to the clear.
Source: 3:7مَا نَنسَخْ مِنْ ءَايَةٍ أَوْ نُنسِهَا نَأْتِ بِخَيْرٍ مِّنْهَآ أَوْ مِثْلِهَا
Naskh is the lifting of an earlier ruling by a later revelation, reflecting the gradual nature of legislation. Scholars distinguish: abrogation of the ruling while the recitation remains (e.g. the waiting period in 2:240 superseded by 2:234); abrogation of recitation while the ruling remains; and abrogation of both. Verified examples are few; later scholars like ash-Shanqiti narrowed the genuine cases considerably. It applies to commands and prohibitions, never to reports about Allah.
Source: 2:106Makki verses are those revealed before the Hijra, and Madani those revealed after it (the most accepted definition is by time, not place). Makki passages tend to be shorter, emphasising tawhid, the Resurrection, and stories of past nations, often addressing "O mankind." Madani passages tend to be longer, detailing law, jihad, social dealings and the hypocrites, often addressing "O you who believe." Knowing this aids tafsir, dating of rulings, and understanding abrogation.
Most surah names are established by the Sunnah and the practice of the Companions; some surahs have several names. Names are often drawn from a striking word or theme within the surah.
The Quran was preserved in three complementary ways: memorised in the breasts of the Companions, written on materials of the time (parchment, palm-stalks, bone), and arranged by the Prophet's instruction.
Under Abu Bakr: after many memorisers were killed at the Battle of al-Yamamah, 'Umar urged compilation; Zayd ibn Thabit gathered the written Quran into a single suhuf, kept with Abu Bakr, then 'Umar, then Hafsah.
Under 'Uthman: as differences in recitation appeared among the new Muslims, 'Uthman ordered standard copies (the Mushaf al-Imam) to be written from Hafsah's suhuf in the dialect of Quraysh, and dispatched them to the major cities, burning conflicting personal copies — uniting the Ummah on one written text.
The Quran was revealed in seven ahruf (modes), a mercy easing recitation for the Arab tribes. The canonical qira'at — seven by Ibn Mujahid, ten by Ibn al-Jazari — are the preserved readings transmitted by mass-narration that fall within the 'Uthmani script.
A reading is accepted as canonical only if it has a sound chain, agrees with Arabic grammar, and conforms to the 'Uthmani Mushaf (even partially). Readings failing these are termed shadhdh (anomalous). The most widespread reading today is Hafs 'an 'Asim.
قُل لَّئِنِ ٱجْتَمَعَتِ ٱلْإِنسُ وَٱلْجِنُّ عَلَىٰٓ أَن يَأْتُوا۟ بِمِثْلِ هَٰذَا ٱلْقُرْءَانِ لَا يَأْتُونَ بِمِثْلِهِ
The Quran challenged its opponents — masters of eloquence — to produce its like, then ten surahs, then a single surah, and none could. Its inimitability is seen in: its sublime linguistic eloquence and order (nazm); its reports of the unseen and future events that came true; its account of past nations without prior study; the absence of contradiction across 23 years of revelation; and indications consonant with natural phenomena.
