Thus he warned all people...
Thus he warned all people, "I shall follow the Prophet's Tradition and execute whatever he had commanded, every gift of which Uthman gave of God's money will be returned to the treasury. Nothing will cancel its belonging to the treasury even if it was married with, or distributed in the wide country. Justice must be implemented, if someone feels hard to accept justice then injustice is harder to accept".
Moreover, he condemned prodigals who run after the pleasures of this life only while disguising in religious masks. In this respect Imam Ali said, "There are some people whom life has absorbed completely. They have built many houses, made rivers, rode beautiful horses, and took to themselves slave-women which brought disgrace upon themselves. Whenever I prevent them from indulging in bad deeds and give them no more than their rights, they turn angry and object furiously.
They say 'Ali ibn Abi Talib has prevented us our rights". Imam Ali’s new policies were aiming at stripping the Quraish completely of their social privileges, financial statuses and authority. This irritated the Quraishite as they no longer enjoyed their garden of Iraq and the rest of the Muslim country and what they have already gained was in danger of being restored to the Muslims’ treasury.
The Quraish not pleased with this new regime and worked continuously to hinder the stabilization of the new authority. Dissents were sent and wars were launched successively, shaking the whole state; economically, socially, politically and morally. Meanwhile, the heads of Quraish who were campaigning against Imam Ali's rule, realized it was not Imam Ali as a person they were fighting, but it was the ideals and policies which he (as) had advocated, it was once again Islam.
Thus the Umayyad's who accepted Islam under various conditions, found that their materialistic thinking couldn’t reconcile with Islamic values, so they decided to distort the Islamic values and ideals, since opposing Islam openly was fatal, as they had experienced previously. Muawiya then ordered the formation of a committee to fabricate Hadiths and distort the interpretation of Qur'an.
Five years had lapsed, which were full of violent events; the battle of camel in Basrah, the battle of Sifsin against Muawiya, the battle of Nahrawan against Khawarij and many other ongoing campaigns. Thus the opposition was able to feed unrest practically in every part of the Islamic State, shaking the authority of the new administration.
