Yaʿqūb ibn Sufyān said in al-Maʿrifah (3/101): “There is no harm in him.”
A number of reliable narrators transmitted from him. See his entry in Tahdhīb al-Mizzī and the commentary on it (11/25–27).
As for Saʿīd ibn Saʿīd, he was Abū al-Ṣabbāḥ al-Taghlibī al-Kūfī. Ibn Ḥibbān likewise mentioned him in al-Thiqāt (6/364), but it appears there as: “... ibn Abī Saʿīd al-Thaʿlabī”! This is an error, as I have explained in Taysīr al-Intifāʿ. This examination of the chains establishes that three reliable narrators transmitted from him: Wakīʿ, Abū Usāmah, and Muḥammad ibn Rabīʿah al-Kilābī. Thus, his hadith is good, Allah willing. The third of them is not mentioned in the two Tahdhīb works and should therefore be added to them. Allah is the Grantor of success.
It has a shorter corroborating narration, worded:
“Whoever invokes blessings upon me of his own accord, Allah will thereby send ten blessings upon him.”
Al-Bazzār narrated it (4/46/3161) through the route of ʿĀṣim ibn ʿUbayd Allāh, from ʿAbd Allāh ibn ʿĀmir ibn Rabīʿah, from his father, attributed to the Prophet with this wording.
ʿĀṣim is weak, as al-Haythamī (10/161) and others stated. Al-Ḥāfiẓ said in Mukhtaṣar al-Zawāʾid (2/440), qualifying this:
“I say: But it is corroborated.”
Perhaps he meant by the first hadith, which is authentic apart from the phrase “of his own accord.” The documentation of some of its chains has been given shortly before.
