The Prophet ﷺ said, "When the ruler seeks out suspicion among the people, he corrupts them."
أن النبي ﷺ قال: إن الأمير إذا ابتغى الريبة في الناس أفسدهم.
Tabarani narrated it in Musnad Shamiyin (1660) from Ahmad bin Mualla (he is the Damascene), who said, "Hisham bin Ammar narrated to us, Ismail bin Ayyash narrated to us," from Damdam bin Zura, from Shurayh bin Ubayd, from Jubayr bin Nufayr and Kathir bin Mura, from Miqdam bin Maadi Kareeb and Abu Umama, and he related it. Its chain of transmission is hasan because of Ismail bin Ayyash, for his hadith is hasan in his narration from the people of Syria, and this is one of them. Likewise Tabarani's teacher Ahmad bin Mualla the Damascene and his teacher Hisham bin Ammar Sulami the Damascene are both truthful (sadooq).Ahmad narrated it (23815) through the route of Baqiya bin Walid, who said, "Ismail bin Ayyash narrated to me," from Damdam bin Zura, from Shurayh bin Ubayd, from Jubayr bin Nufayr and Amr bin Aswad, from Miqdad bin Aswad and Abu Umama, with the same wording. His statement "Miqdad bin Aswad" is an error made by Baqiya bin Walid, and he was not followed on this. The hadith is actually the hadith of Miqdam and Abu Umama.Abu Dawud narrated it (4889) from Saeed bin Amr Hadrami, and Hakim (4/378) narrated it through the route of Muhammad bin Abdul-Aziz Ramli, both of them from Ismail bin Ayyash, who said, "Damdam bin Zura narrated to us," from Shurayh bin Ubayd, from Jubayr bin Nufayr, Kathir bin Mura, Amr bin Aswad, Miqdam bin Maadi Kareeb, and Abu Umama, with the same wording. It occurs there as "and Miqdam and Abu Umama," and this is an old error, since it appears the same way in Tuhfat Ashraf, and likewise in Sunan al-Kubra of Bayhaqi.The correct wording is "from Miqdam and Abu Umama," as it appears with Tabarani in Musnad Shamiyin and with Ahmad in the Musnad, and likewise Ibn Hajar mentioned it with the ambiguous form of transmission ("an") in Ithaf Mahra (17009), and in Atraf Musnad (7392), because it is not conceivable that a follower (tabii) would hear directly from a companion while also linking other followers to him with "and." So the correct version is as I have said. Perhaps this error goes back to Ismail bin Ayyash, for he is not among the reliable memorizers and used to make mistakes in his narrations, so perhaps he is the one who once said "from Miqdam" and another time mentioned it with the conjunction "and Miqdam." Allah knows best what is correct.As for what is narrated from Abu Hurairah, who said that the Messenger of Allah ﷺ said, "One of you sees the speck in his brother's eye but forgets the log in his own eye," the correct position is that this is mawquf (a stopped report, attributed only to the companion).Ibn Hibban narrated it in his Sahih (5761) through the route of Kathir bin Ubayd, who said, "Muhammad bin Himyar narrated to us," from Jafar bin Barqan, from Yazid bin Asam, from Abu Hurairah, who said such and such, and he related it. In this way Muhammad bin Himyar narrated it from Jafar bin Barqan as marfu (attributed to the Prophet).But Kathir bin Hisham Kullabi narrated it, as found with Ahmad in Zuhd (p. 178), and Miskin bin Bukayr Hadhaa Haddani narrated it, as found with Bukhari in Adab al-Mufrad (592), both of them (Kathir bin Hisham and Miskin bin Bukayr) narrating from Jafar bin Barqan with this same chain, but as mawquf.Kathir bin Hisham is reliable (thiqah), and he was declared reliable by Ibn Saad, Ibn Main, Abu Dawud, and others. As for Miskin bin Bukayr, Abu Hatim said of him, "There is no harm in him, he was of sound hadith and used to memorize hadith well," and Abu Dawud and Ibn Main said, "There is no harm in him." As for Muhammad bin Himyar, Ibn Main said of him once that he was reliable, and another time that there was no harm in him, while Abu Hatim said, "His hadith is written down but not relied upon," and Yaqub bin Sufyan said, "He is not strong," and Dhahabi said, "He has unusual and isolated narrations."I say, this is one such instance, since he was not followed in this, but rather was contradicted by someone more reliable and by a greater number of narrators. So perhaps he erred in raising the hadith to the level of marfu, and the correct position is that it is mawquf.
