Reference / Source: (1) This is in Khalifah's "al-Tabaqat" (pp. 26-27).

Technical note / Defect ('illah): He said: "Abu Jandal escaped," and then mentioned it. 'Asim bin 'Umar is a Successor (tabi'i), so this report is "mursal". And the narrator from him is not known; no one other than al-Waqidi narrated from him.
Important point: In any case, this report is "sahih and well-known" among the scholars of biography and military campaigns (al-siyar wa al-maghazi). It is in al-Bukhari (2731) in the narration of al-Zuhri from 'Urwah bin al-Zubayr from al-Miswar bin Makhramah and Marwan bin al-Hakam, but al-Bukhari does not mention the story of Abu Basir's death and the return of that fighting band to Madinah with Abu Jandal.

Reference / Source: However, al-Tabari recorded it in full in his "Tarikh" (2/ 638-639) from the narration of Muhammad bin Ishaq, and al-Bayhaqi in "Dala'il al-Nubuwwah" (4/ 172-175) by way of Musa bin 'Uqbah, both of them from al-Zuhri in "mursal" form.

Reference / Source: Al-Bayhaqi recorded it in "al-Dala'il" (4/ 175-176) by way of Abu al-Aswad (the orphan in the care of 'Urwah bin al-Zubayr), from 'Urwah, in "mursal" form.

Reference / Source: Al-Bayhaqi also recorded it (4/ 172-175) by another route from Musa bin 'Uqbah in "mursal" form. It is also in his "al-Sunan al-Kubra" (9/ 227) by that very same route, but there he did not cite it in full.

Note / Clarification: "al-'Is" (with kasrah on the 'ayn and sukun on the ya'): a valley of the Juhaynah tribe between Madinah and the sea. It flows into "Idam" from the left, from the western edges of Mount al-Ajrad and the adjoining mountains. See further: 'Atiq al-Biladi's "Mu'jam al-Ma'alim al-Jughrafiyyah fi al-Sirah al-Nabawiyyah" (p. 219).
