Technical note / Defect ('illah): (1) The wording between the brackets we have recorded from the narration coming below at no. (8321) and from the sources that transmit the hadith.

Grading: (2) Its chain is sahih.
Technical note / Defect ('illah): Jarir is Ibn Abd al-Hamid, and Mughirah is Ibn Miqsam.

Reference / Source: Al-Nasa'i (5151, 5281) narrated it from Ishaq bin Ibrahim, from Jarir bin Abd al-Hamid, with this same chain.
Details of the narration: In it he coupled some other persons with Ibn Umar, and it is likewise in al-Hakim's narration coming soon at no. (8321), through the route of Yahya bin al-Mughirah al-Sa'di (from Jarir).

Technical note / Defect ('illah): In al-Nasa'i's second narration the name "Abd al-Rahman bin Ibrahim" appears in place of Abd al-Rahman bin Abi Nu'm. Al-Hafiz Ibn Hajar says in "al-Nukat al-Ziraf" (5/477): "I read it like this in al-Mizzi's handwriting in a marginal addition to 'al-Atraf', while in the margin, in the handwriting of al-Husayni, it says: He (al-Mizzi) did not mention this Abd al-Rahman bin Ibrahim in 'al-Tahdhib'; perhaps he is Abd al-Rahman bin Abi Nu'm."

Reference / Source: Ahmad (10/6197) and Abu Dawud (4483) narrated it through the route of Humayd bin Yazid Abu al-Khattab, from Nafi', from Ibn Umar (may Allah be pleased with them both).
Details of the narration: But he was unsure regarding the killing, whether it was the fourth time or the fifth. In Abu Dawud's narration the narrator said: "I think he said on the fifth time: If he drinks it, kill him."
Technical note / Defect ('illah): No one narrated from Humayd bin Yazid except Hammad bin Salamah, and al-Dhahabi said in "al-Mizan": "It is not known who he is."
