Maula Ali (As) did correct the wrongdoings of the previous rulers of Saqeefah, except things which concerned him and his family because he did not want to use the power for his own or his family's benefit.
1. Ameerul Mo'mineen Ali (AS) removed all the wrong, corrupt and unjust rulers who were been appointed by Saqeefah rulers.
2. He removed discrimination between Arabs against non Arab Muslims and between Quraish against other tribes and all sorts of discrimination which was practiced by Saqeefah rulers.
3. He distributed all the wealth among all Muslims equally and did not keep anything for himself or his family.
4. He implemented justice in every case and dispute among Muslims even those were against him.
5, During his rule, poverty diminished among Muslims because he gave the poor their proper rights which led to real social and economic justice.
Wassalam.
