Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Two men cannot be gathered together in the Fire in such a way that one of them is harmed; that Muslim who kills a disbeliever and then continues on the path of righteousness and adopts moderation. Two things cannot be gathered in a servant’s stomach: the dust from the path of Allah and the smoke of Hell. Two things cannot be gathered in a man’s heart: faith and greed.
