In the Name of Allah, The Most Gracious, Ever Merciful.
Love for All, Hatred for None.
God has never willed anything that can be called bad. Whatever He does is all good and nothing but good.
Behold! if there had been nothing like evil in the world, the virtue also would not have existed. Virtue is known by its comparison with evil just as evil is known by its comparison with virtue. For instance, if somebody has the opportunity to commit adultery and at the same time has the power to perpetrate this deed, yet he shuns it, we would call this act of his (to avoid adultery in these circumstances) an act of virtue. If somebody has the opportunity to steal or to do injustice and he is in a position to do these things yet he keeps away from these things he does an act of virtue.
Let it be understood well that to have the opportunity of committing sin and yet avoiding it is virtue and that is what deserves good reward.
