Abū Zurʿah al-Naṣrī rated him reliable.
Abū Ḥātim said, “He is acceptable.”
al-Fasawī remarked, “His reports are ḥasan (fair).”
ʿAbbās related: “I heard Yaḥyā say, ‘Ṣadaqah ibn Yazīd of Damascus transmits acceptable ḥadīth.’”
On the other hand, Aḥmad ibn Ḥanbal, al-Nasāʾī, and others judged him weak.
Ibn ʿAdī commented, “He is nearer to weakness than to trustworthiness.”
I (the author) say: He may well be even weaker than al-Samīn; he has nothing cited in the major collections, and among the most questionable material I have seen for him—in his entry in Tārīkh Dimashq (1)—is the following chain:

Dāwūd ibn Rashīd: al-Walīd ibn Muslim narrated to us, from Ṣadaqah ibn Yazīd, from Yaḥyā ibn Abī Kathīr, from Abū Salamah, from Abū Hurayrah, who said:
“They watched for the new moon and exclaimed, ‘How beautiful! How bright it is!’
The Messenger of Allah (peace and blessings be upon him) said, ‘What will your condition be when your adherence to religion resembles the full moon on the night it is complete, so that none but the sharp-sighted among you can perceive it?’ (2)”

He died a little after 150 AH.
