Please read the narration that the Prophet(pbuh) told about a tribe from Quraish (which is Umayyad ) which will destroy the Muslim Ummah.
We also know some bitter facts in Islamic History that how Banu Umayyad got control on Muslim Ummah. Third Caliph Uthman belongs to Umayyad. This third Caliph gave all higher level designations to Umayyads. Moawiya became so powerful in the result, after the murder of third Caliph, Moawiya became rebellious to Imam Ali, after Imam Ali, Moawiya got control over Islamic state, Moawiya's son Yazid became ruler who killed Imam Hussain, after Yazid the government. remained in Umayyad family.
Muslims need to think those Umayyad who fought against Islam with the Prophet, how come those people got charge of Islamic state?
Please read Muslim with Urdu translation, they clearly wrote about Umayyads. The holy Prophet said: "Better stay away from them"
