The Prophet said: “This religion will be carried in every century by honest men who negate the interpretation of liars, the distortion of exaggerations, and the undue assumption of the ignorant, as bellows negate the malignancy of iron”.
The carrier of the Da’wa:

1. Must know his nation.
2. Must be aware of her nations secrets.
3. Must be informed of the mysteries of her nations psyche set-up.
4. Must be an expert in the methods of instructing her nation.
5. Must know how to address her nation through her nations language.
6. Must know how to be in control of her nations power.
7. Must know how to be the object of her appreciation and respect.

And he cannot do that unless he endeavors to perfect himself.
