Muhammad Ruways transmitted the reading of Ya'qub al-Hadrami, recorded here with Basra as its reading centre, and stands beside Rawh's transmission as the second of the two riwayat through which Ya'qub's reading, one of the three completing the canonical ten, survives.
Ruways's transmission, like Rawh's line of the same reading, permits three modes of joining or pausing at the basmala between suras, holds detached vowel lengthening to two counts against connected lengthening of four or five, and does not include the takbir. Verse numbering follows the Basran count. The surviving technical record does not distinguish the two transmitters on further points beyond these, which is consistent with the pattern among several of the readings Ibn al-Jazari added to the ten: narrower classical commentary survives on the finer distinctions between their two riwayat than for the original seven, where centuries of continuous teaching produced a correspondingly larger body of recorded detail.
Ya'qub's reading entered the canonical register only with Ibn al-Jazari's fifteenth century al-Nashr, five centuries after Ibn Mujahid's original seven, on chains Ibn al-Jazari judged to meet the same tests of soundness, breadth and conformity to an Uthmanic codex. Ruways's transmission accordingly carries the standing of the ten, alongside the other five transmitters of the three readings that completed that wider canon.
