On the authority of Ibn ʿAbbās, he said: The Muslims caught up with a man who had some spoils with him, and he said, "Peace be upon you" (al-salāmu ʿalaykum), but they killed him and took those spoils. Then the verse was revealed: {And do not say to one who gives you [the greeting of] peace, "You are not a believer," seeking the goods of worldly life} [al-Nisāʾ 4:94] — referring to those spoils. (1)

3975 — Saʿīd ibn Manṣūr narrated to us, Ibn Abī al-Zinād narrated to us (ḥ) and Muḥammad ibn Sulaymān al-Anbārī narrated to us, Ḥajjāj ibn Muḥammad narrated to us, from Ibn Abī al-Zinād — and it is more complete — from his father, from Khārijah ibn Zayd ibn Thābit, from his father: That the Prophet, peace and blessings be upon him, used to recite: "other than those with disability" (ghayra ūlī al-ḍarar). (2) And Saʿīd did not say: "he used to recite." (3)

(1) Its chain of transmission is sound. ʿAṭāʾ: he is Ibn Abī Rabāḥ, and Sufyān: he is Ibn ʿUyaynah. Al-Bukhārī (4591), Muslim (3025), and al-Nasāʾī in al-Kubrā (8536) and (11051) also transmitted it via Sufyān ibn ʿUyaynah, with this chain of transmission.
It was also transmitted in a similar manner by al-Tirmidhī (3279) via Simāk, from ʿIkrimah, from Ibn ʿAbbās.
It is found in Musnad Aḥmad (2023) and Ṣaḥīḥ Ibn Ḥibbān (4752).
Ibn Zanjalah said in Ḥujjat al-Qirāʾāt, p. 209: Nāfiʿ, Ibn ʿĀmir, and Ḥamzah recited {li-man alqā ilaykum al-salama} without an alif, meaning: submission and surrender; and it is reported from al-Rabīʿ that he said: reconciliation. The rest recited {al-salāma}, meaning: the greeting. Their proof for this is that the slain man had said to them, "Peace be upon you" (al-salāmu ʿalaykum), and they killed him and took his belongings, so God informed them that the right of one who offers the greeting of peace is that his case be investigated.
(2) The established reading of (ghayra) with accusative case is from (A) and (B), and it was noted in the margin of (H) that it is likewise with accusative in the transmission of Ibn al-Aʿrābī, Abū ʿĪsā al-Ramlī, and al-Luʾluʾī via Abū Dharr.
It was read in (H) as (ghayru) with nominative case. The correct reading, which we have established with accusative, is as stated in Qirāʾāt al-Nabī ṣallā Allāhu ʿalayhi wa-sallam by Abū Ḥafṣ al-Dūrī via Ibn Abī al-Zinād, and as it is vocalized in most transmissions of the Sunan.
(3) A sound ḥadīth, and this chain of transmission is fair (ḥasan) in follow-ups and supporting witnesses on account of Ibn Abī al-Zinād — whose name is ʿAbd al-Raḥmān — for he is weak but considered for corroboration, and he has been followed up. =
