﴿ فَقُولَا لَهُۥ قَوْلًۭا لَّيِّنًۭا لَّعَلَّهُۥ يَتَذَكَّرُ أَوْ يَخْشَىٰ ﴾

“But speak unto him in a mild manner, so that he might bethink himself or [at least] be filled with apprehension.”

(And speak unto him a gentle word) a kind word: �there is no deity except Allah�; it is also said that this means: call him by his agnomen, (that peradventure he may heed) that perhaps he may take admonition (or fear) or surrender [to Allah].
