In spite of what Ibn Abbas advised, Ali issued orders for the deposition of the Governors. Ali appointed Suhail b Hanif as the Governor of Syria; Saad b Ubaidah as the Governor of Egypt; Ummara b Shahab as the Governor of Kufa; Othman b Hanif as the Governor of Basra; and Abdullah b Abbas as the Governor of Yemen. When the nominee of Ali went to Basra, he was able to assume the charge, and no resistance was offered to him. Similarly there was no resistance to the new Governor in Egypt, and he assumed charge without any difficulty. Abdullah b Abbas succeeded in assuming the charge in Yemen, but the previous Governor escaped to Makkah and carried away the entire treasure with him. When the nominee of Ali for the governor of Syria reached Tabuk on the border of Syria, he was met by the Syrian force, who advised him to go back as they did not acknowledge Ali as the Caliph. Similarly the nominee of Ali to the governor ship of Kufa had to return to Madina after having failed to assume the charge of his office.
"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
