SUMMARY
The issue of "divine justice", which is the one of the most important doctrinal principles and a characteristic of the theological religions such Shiite and Mu'tazilite, in fact is one of the Perfect Attributes of Allah and due to its indescribable importance, it has a special place in doctrinal discussions. On the other hand, the existence of evils and calamities, poverty and deprivation, oppression and disease and moral corruption, and even the manner of punishment in the hereafter, always raises doubts in the human mind and calls into question Allah's justice. The generality of such suspicions has led Islamic thinkers to solve these problems in defense of divine justice. In this regard, the present study seeks to use the words of the fourth Shiite Imam in the divine invocations of the complete Sahifa Al_ Sajjadiyya, to achieve the theological foundations to solve some evil doubts in the realm of creation and the human world. The method of collecting materials in this research is library and the research method is "descriptive -analytical". After investigations, it became clear that from Imam Sajjad's point of view, neglecting and inclining the soul to the world and other than Allah, and consequently being caught in the trap of the devil and carnal soul, and contamination with sin and transgression, is the real evil. According to him, the divine test and punishment and return to the truth, the flourishing of talents and the appreciation of blessings are the benefits of evil and suffering. also meanings such as: the inherent richness of the Almighty, the bestowal of goodness and abundant blessings, the guidance of the servants to the good religion and the punishment of the same action in the prayers of Imam (A.S), all three types of genetic justice, legislative justice and criminal justice can be proved.
