On the authority of ʿĀʾishah: that the Messenger of Allah (peace and blessings of Allah be upon him) used to give one taslīm, toward the direction of his face. (1)

920 — Muḥammad ibn al-Ḥārith al-Miṣrī narrated to us, Yaḥyā ibn Rāshid narrated to us, from Yazīd, the freed slave of Salamah, from Salamah ibn al-Akwaʿ, who said: I saw the Messenger of Allah (peace and blessings of Allah be upon him) pray, and he gave the taslīm once. (2)

Chapter 30: On Responding to the Imām’s Salām

921 — Hishām ibn ʿAmmār narrated to us, Ismāʿīl ibn ʿAyyāsh narrated to us, Abū Bakr al-Hudhalī narrated to us, from Qatādah, from al-Ḥasan—

(1) Its chain is weak; Zuhayr ibn Muḥammad — namely al-Tamīmī — his narration as transmitted by the people of Syria is not sound, and ʿAbd al-Malik is Syrian, with some criticism concerning him as well.
It was also recorded by al-Tirmidhī (296) via the route of ʿAmr ibn Abī Salamah al-Shāmī, from Zuhayr, with this chain. And it is in "Ṣaḥīḥ Ibn Ḥibbān" (1995).
Aḥmad (25987) and (25988) recorded via the route of Bahz ibn Ḥakīm, from Zurārah ibn Awfā, from Saʿd ibn Hishām, from ʿĀʾishah, in the description of his prayer (peace and blessings of Allah be upon him) at night: that he used to give one taslīm. And that is a sound ḥadīth.
His giving one taslīm (peace and blessings of Allah be upon him) has a supporting witness from the ḥadīth of Anas, recorded by al-Bayhaqī 2/179, and its narrators are trustworthy.
And another from the ḥadīth of Ibn ʿUmar, recorded by Aḥmad (5461), concerning his taslīm between the odd-numbered rakʿahs and the witr at night, and its chain is strong.

(2) Its chain is weak due to the weakness of Yaḥyā ibn Rāshid: namely al-Māzinī al-Baṣrī. Yazīd, the freed slave of Salamah: he is Ibn Abī ʿUbayd al-Aslamī.
It was also recorded by al-Bayhaqī 2/179 via the route of Muḥammad ibn al-Ḥārith, with this chain.
