Sahih Adab al-Mufrad

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Abu Bakr is a very good man, Umar is very good, Abu Ubaidah is a very good man, Usayd bin Hudayr is very good, likewise Thabit bin Qais bin Shammas is a very good man, Mu'adh bin Amr bin Jamuh is a very good man, Mu'adh bin Jabal is a very good man." He said: "And such-and-such a man is bad, and such-and-such a man is bad," until he counted seven men.
