In the Holy Quran, Allah, the Lord of Glory, has stated:
﴿فَإِن فَاءَتْ فَأَصْلِحُوا بَيْنَهُمَا بِالْعَدْلِ وَأَقْسِطُوا ۖ إِنَّ اللَّهَ يُحِبُّ الْمُقْسِطِينَ﴾
"So if they repent, then make reconciliation between them justly, and act justly. Indeed, Allah loves those who act justly."
Reference: (49-Al-Hujurat:9)
In this noble verse, Allah Almighty has given glad tidings of His love to those who act with justice and fairness.
On the Day of Judgment, among the fortunate ones whom Allah will grant a place under the shade of His Throne, one will be a just ruler.

Regarding those who act with justice and fairness, the Prophet Muhammad (peace be upon him) said:
إن المقسطين، عند الله على منابر من نور، عن يمين الرحمن عز وجل، وكلتا يديه يمين، الذين يعدلون فى حكمهم وأهليهم وما ولوا
"Indeed, those who act justly will be with Allah, on pulpits of light, on the right side of the Most Merciful, and His two hands are on the right. That is, those people maintain justice in their judgments, among their family members, and in the tasks entrusted to them."

Sayyiduna Abu Hurairah (may Allah be pleased with him) reports that the Prophet Muhammad (peace be upon him) said:
كل سلامى من الناس عليه صدقة، كل يوم تطلع فيه الشمس، يعدل بين الناس صدقة
"Charity is obligatory on every joint of a person every day the sun rises, and judging between two people justly is charity."
