That was when they endeavoured to tempt the Hashimites to claim caliphate so as to create sedition and riot, but caution and awareness of al-Imam Ali (A) thwarted their intrigue, when they retreated lying in wait for the opportune time, That was during the caliphate of Uthman, who as soon as assuming the power, the Umayyads showed up what their breasts harboured, And as Uthman was an Umayyad, they embarked on executing their plan so accurately and skillfully till dominating and controlling all the affairs in his time.

In the last years of his rule the government system turned over from just caliphate to a rule being the sport of desires and a plaything passed from design to another.

When after the death of Uthman, dissension stirred up and insurrection blazed hard, with people dividing into belligerent sects and parties, every group of people started to support and back their party with every available means of material, abstract and verbal backing, some taking the side of the Hashimites and the others following the Umayyads, and so on.

It was found that the strongest weapons for defeating others and achieving victory, was that every community should have recourse to evidences reported from the Prophet for backing up their sect and reinforcing what it calls to. For all this, they all embarked on narrating some traditions they ascribed to the Messenger (upon whom be God's benedictions), particularly on virtues, as was previously indicated when discussing the reasons of fabrication of hadith.

That was not to be done by them but only due to the fact that they realized the Messenger's solemn and imposing character, and his status being above every other status. But triumph was for the Umayyads over the Hashimites, because of the power and artifice they had, and what they possessed of wealth, influence and subduing force.

There is another aspect having an effective role in sporting with riwayah, which was represented by those who were disguising under the religious garment, with the aim of corrupting the pristine religious beliefs, through foisting into them estranged things, and inserting falsified teachings that distorted their picture.

These were the people of the Scripture (Ahl al-Kitab) including the Jews and Christians, who deceptively showed Islam, while slipping into the new religion of Arabs (Islam) what their treachery and lust ordered them to insert of Israiliyyat, Masihiyyat and lies, as stated before.
