Grading: This hadith is "qawi" (strong), (but) this particular chain is "da'if" because of Muslim bin Khalid, who is al-Zanji.
Technical note / Defect ('illah): He also used to narrate it with "Abd al-Rahman bin Ishaq bin Abdullah" (whose nickname is Abbad) as an intermediary between himself and Abu Hazim (whose name is Salamah bin Dinar al-Madani). Al-Zanji has been corroborated in this hadith.

Reference / Source: Al-Tahawi narrated it in "Sharh Mushkil al-Athar" (4941) from al-Rabi' bin Sulayman al-Muradi and Nasr bin Marzuq, both of them from Asad bin Musa, with this same chain.

Reference / Source: Abu Bakr al-Shafi'i narrated it in "al-Ghaylaniyyat" (606) through the route of Abd al-Samad bin al-Nu'man, from Muslim al-Zanji, with this same chain.

Technical note / Defect ('illah): A group of narrators contradicted the two of them: they narrated it mentioning "Abbad bin Ishaq" between Muslim al-Zanji and Abu Hazim.
Reference / Source: It was narrated in this way by Imam Ahmad (37/22875) from Husayn bin Muhammad; by al-Ruyani in his "Musnad" (1051), al-Tahawi (4942), al-Tabarani in "al-Kabir" (5767), Ibn Adi in "al-Kamil" (4/303 and 6/309), al-Daraqutni (3155) and al-Bayhaqi (8/251) through the route of Hisham bin Ammar; by al-Daraqutni (3155) through the route of Yunus bin Muhammad; and by al-Daraqutni (3155) and al-Khatib in "Tarikh Baghdad" (5/197) through the route of Abu Ali Ahmad bin al-Hakam. These four narrators narrate it from Muslim bin Khalid al-Zanji, from Abd al-Rahman bin Ishaq (known as Abbad), from Abu Hazim, from Sahl bin Sa'd (may Allah be pleased with him).
Details of the narration: The wording of Imam al-Tahawi's narration is: "A woman came to the Prophet (peace and blessings be upon him) and said: So-and-so committed adultery with me. The Prophet (peace and blessings be upon him) sent for that man and asked him, but he denied it, so he stoned the woman." This narration is "mistaken". In the narration of Hisham bin Ammar and Ahmad bin al-Hakam too, the words "he stoned him" appear in place of "he applied the hadd to him"! Al-Daraqutni did not quote the wording of Yunus's narration.
Grading: The narration of the group who narrate from al-Zanji is more worthy (of preference), especially since it agrees with the narration of Abd al-Salam bin Hafs, whose wording is: "So he had him flogged with the lashes of the hadd." Abu Dawud (4437, 4466) and al-Tabarani (5924) narrated it through the route of Uthman bin Abi Shaybah, from Talq bin Ghannam, from Abd al-Salam bin Hafs, from Abu Hazim, with this same chain, and this chain is strong.

Note / Clarification: This Aslami man is Ma'iz bin Malik al-Aslami. His story has already passed from several Companions; see the previous hadiths nos. (8275-8281).

Reference / Source: And on the topic of carrying out the hadd on the one who confesses and leaving the other (if he does not confess), there are narrations from Abu Hurayrah and Zayd bin Khalid (may Allah be pleased with them both) in al-Bukhari (2695) and Muslim (1697).
