Al-Hākim declared, “Its chain of transmission is sound,” and al-Dhahabī concurred; and the assessment is indeed correct.
It also has a corroborating report from Ibn ʿUmar with similar wording, which al-Nasāʾī recorded with an authentic chain.
102 — “Post-prayer invocations that will never let the one who recites—or performs—them be disappointed after every prescribed prayer: thirty-three declarations of subḥānallāh (Glorified is Allah), thirty-three declarations of al-ḥamdu lillāh (All praise is due to Allah), and thirty-four declarations of Allāhu akbar (Allah is the Greatest).”

It was narrated by al-Tirmidhī (1/353), al-Dāramī (2/215), al-Ḥākim (4/164), Aḥmad (2/168), and Ibn Bishrān in al-Amālī (143/1) on the authority of Ḥaywah and Ibn Lahiʿah, who said:
