The formulas of delivery (1) are: samiʿtu (“I heard”), ḥaddathanī (“He narrated to me”); then akhbaranī (“He informed me”); qaraʾtu ʿalayhi (“I read to him”); next, quriʾa ʿalayhi wa-anā asmaʿu (“It was read to him while I was listening”); then anbaʾanī (“He apprised me”); nawalani (“He handed the text to me”); shāfahanī (“He addressed me directly”); kataba ilayya (“He wrote to me”); and finally ʿan (“from”) and the like.
The first two are employed by one who heard the shaykh’s very words by himself; if the session was held in company, the narration is understood to have been shared with others (2).
Of all these, the very first formula is the most explicit (3) and enjoys the highest status when the material is being dictated.
The third and fourth expressions are used by a student who reads the text aloud himself. When the reading is done collectively, it is treated as the fifth formula (4).
Inbāʾ (5) originally carries the same meaning as ikhbār (6); however, in the usage of the later scholars it (7) designates an ijāzah (permission to transmit) (8), just like the formula ʿan.
The ʿanʿanah (citing a link with “ʿan”) of two contemporaries is presumed (9) to indicate direct audition, except when the transmitter is a mudallis (one who conceals his source) (10). Another view requires proof that the two actually met (11), even if only once (12)—and this is the preferred opinion.
