And go not nigh to fornication; surely it is an indecency and an evil way.

And when We bestow favor on man, he turns aside and behaves proudly, and when evil afflicts him, he is despairing.

Whoever brings a good deed, he shall have ten like it, and whoever brings an evil deed, he shall be recompensed only with the like of it, and they shall not be dealt with unjustly.

Then there came after them an evil posterity who inherited the Book, taking only the frail good of this low life and saying: It will be forgiven us. And if the like good came to them, they would take it (too). Was not a promise taken from them in the Book that they would not speak anything about Allah but the truth, and they have read what is in it; and the abode of the hereafter is better for those who guard (against evil). Do you not then understand? / And (as for) those who hold fast by the Book and keep up prayer, surely We do not waste the reward of the right doers.

Surely man is created of a hasty temperament / Being greatly grieved when evil afflicts him / And niggardly when good befalls him / Except those who pray, / Those who are constant at their prayer / And those in whose wealth there is a fixed portion.

Fighting evil with evil doesn't diminish it; rather, it increases the evil.
