Tirmidhi 3271

[Hasan] Ibn Majah also narrated it in Zuhd, chapter on scrupulousness and piety, no. 4219, from the hadith of Yunus with the same wording, but its chain is daif. Hakim graded it sahih according to the standard of Bukhari (2/163), and Dhahabi agreed with him, while Baghawi graded it hasan. The hadith has corroborating narrations found in Nasai (6/64, no. 3227) and Qudai in Musnad Shihab (1/46, no. 20), among others.
