Shaykh Al-Islam Ibn Taymiyah (may Allaah have mercy on him) said, “The one who enjoins what is good and forbids what is evil must understand what he is enjoining and what he is forbidding; he must be gentle when enjoining and gentle when forbidding; he should be forbearing when enjoining and forbearing when forbidding.
So he should understand before he enjoins what is good and forbids what is evil; being gentle when enjoining is most likely to achieve the desired outcomes; and forbearance after enjoining will enable him to be patient in bearing the reaction of the one whom he enjoins or forbids, because the reaction will often be offensive and rude.
Hence Allaah says, “Enjoin (on people) Al‑Ma‘roof (Islamic Monotheism and all that is good), and forbid (people) from Al‑Munkar (i.e. disbelief in the Oneness of Allaah, polytheism of all kinds and all that is evil and bad), and bear with patience whatever befalls you.” [Luqmaan 31:17]” Ref: Majmoo’ al-Fataawa (15/167)
Also Shaykh Al-Islam Ibn Taymiyah (may Allaah have mercy on him) has said topic, “These three are essential: knowledge, kindness and patience: knowledge before enjoining or forbidding, kindness when doing so and patience afterwards, as it was narrated that one of the salaf said: No one can enjoin what is good or forbid what is evil unless he understands what he is enjoining or forbidding, and is kind in enjoining and kind in forbidding, and is patience and forbearing when enjoining and when forbidding.” Ref: Majmoo’ al-Fataawa, 28/137
Additionally it was narrated that Sufyaan Al-Thawri (may Allaah have mercy on him) said, “No one should enjoin what is good and forbid what is evil except the one who has three characteristics: he is gentle when enjoining and gentle when forbidding; just when enjoining and just when forbidding; and he has knowledge of what he is enjoining and what he is forbidding.” Ref: Jaami’ al-‘Uloom wa’l-Hukam (p. 325).
