You would cry out to the heavens against his sinfulness. Even if there were one innocent man and nine criminals aboard the ship, it would be against all rules of justice to sink it.

So too, if there are in the person of a believer, who may be compared to a dominical dwelling, a Divine ship, not nine, but as many as twenty innocent attributes such as belief, Islam, and neighbourliness; and if you then nurture rancour and enmity against him on account of one criminal attribute that harms and displeases you, attempting or desiring the sinking of his being, the burning of his house, then you too will be a criminal guilty of a great atrocity.

SECOND ASPECT

They are also sinful in the view of wisdom, for it is obvious that enmity and love are opposites, just like light and darkness; while maintaining their respective essences, they cannot be combined.

If love is truly found in a heart, by virtue of the predomination of the causes that produce it, then enmity in that heart can only be metaphorical, and takes on the form of compassion. The believer loves and should love his brother, and is pained by any evil he sees in him. He attempts to reform him not with harshness but gently. It is for this reason that the Hadith of the Prophet says, "No believer should be angered with another and cease speaking to him for more than three days," (4)
