in its matn (corroborated through the well-known accounts of the Farewell Sermon), though this particular isnād is Ḍaʿīf.
Chain: Wakīʿ ibn al-Jarrāḥ → Salamah ibn Nubayṭ ibn Sharīṭ → his father Nubayṭ ibn Sharīṭ (may Allah be pleased with him). Rijāl: (1) Wakīʿ: Wakīʿ ibn al-Jarrāḥ al-Ruʾāsī (d. 197 AH); thiqah ḥāfiẓ, precise and devout. (2) Salamah ibn Nubayṭ ibn Sharīṭ al-Ashjaʿī: graded variously by the critics, with some grading him ṣadūq and others noting weakness in his narrations, which is reflected in the stated grading here. (3) Nubayṭ ibn Sharīṭ al-Ashjaʿī: a Companion who performed the Farewell Pilgrimage (Ḥajjat al-Wadāʿ) with the Prophet ﷺ. Takhrīj: the underlying event — the Prophet’s ﷺ delivering the Farewell Sermon on the Day of ʿArafah while mounted on his she-camel al-Qaṣwāʾ — is extensively and soundly documented in Muslim’s lengthy ḥadīth of Jābir ibn ʿAbdullāh describing the Farewell Pilgrimage (1218), and in Abū Dāwūd (1905), so the matn is firmly established even though this particular isnād through Salamah ibn Nubayṭ is weak. Commentary: The Prophet’s ﷺ choice to deliver this momentous sermon from atop his mount, addressing the vast assembly of pilgrims, reflects both practical necessity (being seen and heard by such a large crowd) and the solemn, historic nature of the occasion — his final address to the Muslim community.
