122. This instruction is very important for those who are engaged in the propagation of Islam. They should always keep in view two things, wisdom and excellent admonition. Wisdom implies that one should use discretion in the work of propagation and should not do this blindly like foolish people. Wisdom demands that one should keep in view the intelligence, capability and circumstances of the addressees and convey the message in accordance with the requirements of the occasion. Moreover, one should refrain from applying one and the same method to each and every person or group but should first diagnose the real disease of the addressee and then cure it by appealing to his mind and intellect.
Excellent admonition implies two things:
(1) One should not be content with convincing the addressee with arguments alone but should also appeal to his feelings. Likewise one should not confine himself merely to arguments in condemning evils and deviations but should try to convince the other of their repugnance that lies embedded in the human nature. One should also warn of the worst consequences of those evils. Besides, one should not only try to convince the addressee rationally of the soundness and excellence of guidance and righteous deeds but should also create in him interest and love for them.
(2) Admonition should be administered in such a manner as to show sincere concern for and the welfare of the addressee. Nothing should be said or done to create the impression that the admonisher is looking down upon him and taking pleasure in his own feeling of superiority. On the contrary, he should feel that the admonisher is filled with the strong desire for his reform and welfare.
