A part of Da’wah is to “forbid the evil.” Necessarily then, at times, the Da’i will have to tell people that certain things are Haram (prohibited). When this is done, Halal (permissible) alternatives should be provided.
Allah says, “O you who have believed, say not [to Allah ‘s Messenger], ‘Ra’ina’ but say, ‘Unthurna’ and listen…” (Qur’an 2:104)
Here Allah told them what not to say and then immediately provided them with an alternative to say.
The Prophet (SallAllhu ‘Alayhi wa Sallam) also used to forbid and give alternatives.
Abu Sa’id al-Khudri and Abu Hurayrah narrated: The Messenger of Allah (SallAllahu ‘Alayhi wa Sallam) appointed a man as an agent in Khaybar, and he brought him some excellent dates. The Messenger of Allah (SallAllahu ‘Alayhi wa Sallam) said to him, “Are all the dates of Khaybar like this?” He said, “No. By Allah, Messenger of Allah! We take a sa of this kind for two sa or two sa for three.” The Messenger of Allah (SallAllahu ‘Alayhi wa Sallam) said, “Do not do that. Sell the assorted ones for dirhams and then buy the good ones with the dirhams.” (Muwatta 1314)
Here the Prophet (SallAllahu ‘Alayhi wa Sallam) told them what not to do and then immediately provided an alternative on what they can do.
This principle was also followed by the Companions.
Sa`id bin Abu Al-Hasan narrated: While I was with Ibn `Abbas a man came and said, “O father of `Abbas! My sustenance is from my manual profession and I make these pictures.” Ibn `Abbas said, “I will tell you only what I heard from Allah’s Messenger (SallAllahu ‘Alayhi wa Sallam). I heard him saying, ‘Whoever makes a picture will be punished by Allah till he puts life in it, and he will never be able to put life in it.’” Hearing this, that man heaved a sigh and his face turned pale. Ibn `Abbas said to him, “What a pity! If you insist on making pictures I advise you to make pictures of trees and any other unanimated objects.” (Bukhari 2225)
Know that whenever Allah has made something Haram, He has made many more things Halal. Consider in terms of drink, Allah has made alcoholic drinks Haram, but He has allowed water, milk, tea, coffee and all kinds of fruit and vegetable juices.
Da’wah Tip Summary: Whenever you point out something is Haram, provide a Halal alternative.
