The Prophet Muhammad (peace and blessings of God be upon him) said:
“If two Muslims meet each other with their swords, then both the killer and the killed will be in the Hell-fire.”
Someone then said:
“O God’s Messenger, that is the case for the killer but why should that be the case for the killed?”
He (peace and blessings of God be upon him) replied:
“Because he wanted to kill his companion.”

I pray to God that the Muslims stop fighting each other and start helping each other build their communities and putting families back together. Ameen!
