SHAFAQNA – Imam Ali (AS) said: If people are against the government, and the ruler oppresses the people, the unity will be destroyed; the signs of oppression appear; and deceitfulness in religion will spread; and the broad way of the traditions of the Prophet (PBUH) will be abandoned; lot of people will follow their own desires; religious decrees will be abandoned, and there will be a lot of illnesses of the heart; people will not worry if a big just case is forgotten and a dangerous injustice spread in society; then at that time the good people, will be disrespected, and bad people will become powerful; and the Divine Punishment for creatures will be great and painful [1].
