Allah orders to abide by equity, justice and Ihsaan

[Sayfullah]

Allah said in soortaun Nahl, 90:

إِنَّ اللَّهَ يَأْمُرُ بِالْعَدْلِ وَالْإِحْسَانِ وَإِيتَاءِ ذِي الْقُرْبَى وَيَنْهَى عَنِ الْفَحْشَاءِ وَالْمُنْكَرِ وَالْبَغْيِ
Allah orders to abide by equity, justice and Ihsaan and to support the kinship. He orders to refrain from enormous sinful doings, blasphemy and aggression.

Ihsaan is to give people who have right their rights and add on the top of the obligated right out of one's generosity because the reward for Ihsaan is Ihsaan and the favor is returned by a better favor.
