CALLING TO GOD
Call to the way of your Lord with wisdom and fair exhortation and reason with them in a way that is best. Your Lord knows best those who have strayed away from His path, and He knows best those who are rightly guided. If you want to retaliate, retaliate to the same degree as the injury done to you. But if you are patient, it is better to be so. Endure with patience; truly, your patience is possible only with the help of God. Do not grieve for them, or feel distressed because of their plottings, for God is with those who are righteous and those who do good.
(16:125-128)
