Ali held that the people are the main power, and they have the right to criticize the government. The government should work for the welfare of the people and should keep them satisfied. Ali was particular that the minorities should be well cared for and their rights should be kept safeguarded. The minorities should have the freedom of worship, and they should enjoy autonomy in the administration of their own affairs. Ali held that it was the obligation of the state to look after the destitute and the distressed. He attached particular importance to the care of the widows and the orphans.
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
Sahih Bukhari
