Note / Clarification: The one meant here is "al-Qasim bin Sallam", from whom 'Ali bin 'Abd al-'Aziz al-Baghawi narrates. This report was narrated by both "Abu 'Ubayd al-Qasim bin Sallam" and "Abu 'Ubaydah Ma'mar bin al-Muthanna", as will come. Al-Dhahabi mentioned it in "al-Siyar" (2/ 256) from al-Qasim bin Sallam Abu 'Ubayd, while Ibn 'Abd al-Barr in "al-Isti'ab" (p. 910) and Ibn Hajar in "al-Isabah" (4/ 1865) mentioned it from Abu 'Ubaydah Ma'mar bin al-Muthanna.

Reference / Source: Al-Daraqutni recorded it in "al-Mu'talif wa al-Mukhtalif" (3/ 1320) by way of Ibn Abi Khaythamah, who said: al-Athram Abu al-Hasan mentioned from Abu 'Ubaydah Ma'mar bin al-Muthanna.

Reference / Source: Ibn Mandah recorded it in "Ma'rifat al-Sahabah" (p. 978) — and by way of him Ibn 'Asakir in his "Tarikh" (3/ 230) — by way of 'Abd al-Wahid bin 'Abd Allah al-Muharibi, from Hafs bin al-Nadr, from Qatadah, who said: "The Messenger of Allah (peace and blessings be upon him) married Saba bint Asma' bin al-Salt al-Sulamiyyah."

Reference / Source: Abu Nu'aym in "Ma'rifat al-Sahabah" (7467) and al-Bayhaqi in "al-Dala'il" (7/ 288) recorded it by way of Zuhayr bin al-'Ala', from Sa'id bin Abi 'Arubah, from Qatadah, who said: "He (peace and blessings be upon him) married Asma' bint al-Salt, of Banu Haram of Banu Sulaym, and she died before he consummated the marriage."
Grading: Note that Zuhayr is a "da'if" narrator, as has passed more than once. Then he said: And Hafs bin al-Nadr narrated from Qatadah (about the name): "He (peace and blessings be upon him) married 'Saba' bint Asma' bin al-Salt al-Sulamiyyah."
