To the path of your Lord, to Islam, with wisdom by the sound and correct words, which is the clear evidence of the truth that removes doubt. And the good advice, which is that it is not hidden from them that you advise them with it and intend what benefits them therein. It is permissible that he means the Qur'an, that is: call them with the Book which is wisdom and good advice. And argue with them in the best way, by the method that is the best of ways of arguing, with gentleness and kindness, without harshness or reprimand. Indeed, your Lord knows best about them. So whoever has goodness in him, a little admonition and gentle advice is enough for him. And whoever has no goodness in him, the means will fail against him, as if you were striking iron that is cold.
