It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "On the night of Bara’ah, Allah Almighty looks upon His creation and forgives all His servants, except for two people: those who harbor enmity and hatred towards each other, and the murderer."
