I say: The apparent reason is that they are unknown, for Ibn Abi Hatim listed Mus‘ab ibn ‘Ubayd Allah ibn Junadah and his father (4/1/306 and 2/2/310), as had al-Bukhari before him (4/1/353 and 1/375), yet neither mentioned any criticism or accreditation concerning them. Al-Haythami likewise did not recognize them (3/13).

It is also corroborated by the hadith of Karīmah al-Muzaniyyah, who said: I heard Abu Hurayrah, while he was in the house of Abu al-Darda’, say—then she cited it as being attributed to the Prophet—with the wording: “Three acts are disbelief in Allah: tearing one’s garment at the breast, wailing, and impugning one’s lineage.” Al-Hakim narrated it (1/383) and said: “Its chain of transmission is authentic.” Al-Dhahabi concurred with him, although he had said in the biography of this Karīmah in al-Mizan: “Isma‘il ibn ‘Ubayd Allah ibn Abi al-Muhajir alone narrated from her,” indicating that she is unknown. Nevertheless, Ibn Hibban declared her trustworthy, and that is not unusual for him. What is strange, however, is that al-Hafiz Ibn Hajar concurred with him, saying in her biography in al-Taqrib: “Trustworthy!” even though no one besides Ibn Hibban declared her trustworthy. My experience of him in comparable cases involving narrators whom Ibn Hibban alone declared trustworthy is that he calls them “acceptable” or “unknown.” This accords with his detailed remarks in the introduction to his book Lisan al-Mizan regarding Ibn Hibban’s accreditation, namely that he declares unknown narrators trustworthy. Refer to it, if you wish.

It has other corroborating reports as well: from the hadith of ‘Amr ibn ‘Awf, narrated by al-Bazzar (no. 798), and of Salman al-Farisi, narrated by al-Tabarani (6100), among others. Al-Haythami discussed their chains of transmission (3/13).

1802 — “There are three ruinous traits and three saving traits.” He said: “The three ruinous traits are an obeyed greed, a followed desire, and a person’s admiration of himself. The three saving traits are fear of Allah in private and in public, moderation in poverty and wealth, and justice in anger and contentment.”
