due to interruption (inqiṭāʿ) in the chain.
Chain: Abū Bakr ibn ʿAyyāsh → ʿĀṣim ibn Abī al-Najūd → al-Ḥārith ibn Ḥassān al-Bakrī (may Allah be pleased with him). Rijāl: (1) Abū Bakr ibn ʿAyyāsh al-Asadī: thiqah thabt, one of the most celebrated reciters (qurrāʾ) of Kūfah, though some critics noted his memory in ḥadīth (as distinct from his mastery of recitation) grew less precise in old age. Died c. 193 AH. (2) ʿĀṣim ibn Abī al-Najūd al-Kūfī: himself among the seven canonical reciters of the Qurʾān, graded ḥasan al-ḥadīth by most critics though a small number noted minor confusion in his transmissions outside of recitation; the specific weakness in this chain is identified as an interruption (inqiṭāʿ), meaning ʿĀṣim did not hear this report directly from al-Ḥārith. (3) Al-Ḥārith ibn Ḥassān al-Bakrī: a Companion. Takhrīj: while this specific report is uncorroborated in the six canonical collections, the broader picture of Bilāl standing in ceremonial attendance upon the Prophet ﷺ, and of black banners marking returning expeditions, finds general parallels in the sīrah and maghāzī literature describing ʿAmr ibn al-ʿĀṣ’s campaigns following his acceptance of Islam in 8 AH. Commentary: Though this chain is interrupted and therefore weak as a matter of strict isnād criticism, it preserves a memorable visual scene from Madīnah — the Prophet ﷺ upon his pulpit with Bilāl armed and standing guard, and the black banners announcing the return of ʿAmr ibn al-ʿĀṣ, the future conqueror of Egypt — valuable as a historical vignette even where the chain itself does not meet the standard for ḥadīth authentication.
