Quran 49:9 — The Walls (Al-Hujurat)

If two groups of believers fought with each other, you shall reconcile them. If one group aggresses against the other, you shall fight the aggressing group until they submit to GOD's command. Once they submit, you shall reconcile the two groups equitably. You shall maintain justice; GOD loves those who are just.

[49:8] Such is grace from GOD and His blessings. GOD is Omniscient, Most Wise.

[49:10] The believers are members of one family; you shall keep the peace within your family and reverence GOD, that you may attain mercy.
