A suggested objection concerning “Actions are by intentions” is that ʿUmar publicly narrated it among Companions, none objected, and therefore those present might be treated as supporting transmitters. That reasoning confuses possible hearing with actually documented transmission.
The presence of additional listeners does not establish that each heard, preserved, and transmitted the same report through a distinct isnad. The absence of a recorded objection likewise does not create a new chain.
Routes must be counted from established transmission, not hypothetical possibilities. The distinction is equally relevant to a public sermon or announcement heard by many people but preserved through one demonstrable narrator.
Ibn Rushayd’s rebuttal: Responding to Ibn al-ʿArabi’s attribution of the condition to al-Bukhari, Ibn Rushayd pointed to the very first hadith in Sahih al-Bukhari, «إِنَّمَا الْأَعْمَالُ بِالنِّيَّاتِ», whose early transmission is singular at successive stages. Al-Bukhari therefore cannot be said to require two independent narrators at every stage. Nor can an audience that did not demonstrably transmit the report be counted as an additional established isnad.
