Al-Susi an Abu Amr

Salih al-Susi transmitted the reading of Zabban Abu Amr al-Basri, one of the seven canonical readers, recorded here with Basra as its reading centre, the same city as Abu Amr's own. Classical sources place al-Susi's transmission through the intermediate link of al-Yazidi, the Basran reader whose own name also carries an independent shadhdh reading elsewhere in this register; al-Susi's line stands beside al-Duri's as the two riwayat through which Abu Amr's reading survives among the seven.

The transmission softens the second of two adjacent hamzas and, distinctively, also replaces a quiescent glottal stop with a plain long vowel in certain positions, a second recorded hamza classification alongside the first. It applies the greater assimilation systematically rather than in isolated cases, applies imala in only a small number of words, and holds detached vowel lengthening to two counts against four or five at connected junctures. The closing mim of plural pronouns is left silent, no light pause is observed, and the basmala's treatment between suras follows three permitted modes rather than a single fixed practice. Verse numbering follows the Basran count.

As one of Abu Amr's two seven canon transmitters, al-Susi's reading carries the same standing as the six other principal lines Ibn Mujahid selected, among the readings judged mutawatir by the breadth and number of their independent chains.
