Classical Sunni sources preserve a report that a pot or vessel associated with Abu al-Darda, may Allah be pleased with him, produced an audible sound of tasbih, with Salman al-Farsi, may Allah be pleased with him, connected to the scene. Al-Lalaka'i preserves a Khaythama route and later places the event among the karamat of Abu al-Darda and Salman, while al-Dhahabi reproduces that form and explicitly judges the report sound. A fuller Ibn Abi Shaybah version adds that the pot overturned and returned without spilling, but that route is disconnected. A separate plate or bowl version also exists through Qays ibn Abi Hazim, yet it is hearsay at the Companion link and should remain distinct from the pot report.
The account then gives Salman's response after the sound ceased. He is reported to have remarked that, had it continued, Abu al-Darda would have heard or seen even greater signs of Allah. Al-Lalaka'i includes the incident in his section on the karamat of Abu al-Darda and Salman, which explains the way the story was received in classical Sunni literature. Al-Dhahabi later reproduces the Khaythama form in Tarikh al-Islam and explicitly describes the report as sound, giving meaningful positive support to this principal version.
Other classical routes preserve additional details, but they should not be silently merged into one reconstructed story. Musannaf Ibn Abi Shaybah contains a fuller form through Abu al-Bakhtari in which the pot overturns and then returns to its place without spilling its contents. The checked edition, however, notes that Abu al-Bakhtari did not meet Abu al-Darda, making that particular route disconnected.
A related report describes Abu al-Darda and Salman eating from a plate or bowl whose vessel and contents glorified Allah. That version comes through Qays ibn Abi Hazim and is introduced as something people used to relate. Classical biographical material also states that Qays did not hear from Abu al-Darda or Salman, so this parallel has a different evidentiary status from the principal pot report.
The strongest public conclusion is therefore cautious but positive. Classical sources preserve a Companion karamah in which audible tasbih was associated with Abu al-Darda's vessel, with Salman linked to the event, and al-Dhahabi positively grades the principal Khaythama form. The fuller overturning-pot and plate versions remain related but weaker route variants. The report should be presented as a Companion athar or karamah, not as a sahih Prophetic hadith.
Conclusion
Classical Sunni sources preserve a report of audible tasbih from a vessel associated with Abu al-Darda, with Salman al-Farsi connected to the scene, and al-Dhahabi positively grades the principal route. Because related fuller variants carry disconnection or hearsay, the event is best included with caution as a medium-confidence Companion karamah.
