Prophet (S) said: no nation strays after guidance, save it engages in dispute.

Avoid fussing because in this way you impassion the ignorant against yourself, and destroy brotherhood.[^5] The ill effects of discussions mixed with dispute and aggression are precisely studied in the above traditions and it is inferred from them that: 1- Dispute in discussion is useless, and it has no result (because hurting affections of the other party causes him to resist).

2- Dispute is not compatible with belief (because it is the sign of arrogance and seeking excellence, and arrogance is never compatible with belief, the sense of which is submission and surrender to the truth). 3- Dispute results in sedition and attracting enmity and hostility (because everyone is sensitive and strict for ruining of his personality). 4- Dispute causes misguide (because it excites the sense of obstinacy, selfishness, and prejudice and thereby covers the visage of truth).

5- If dispute is made with the ignorant, it encourages them to violate the reverence of one's personality and makes them insolent to him (because when they find their reputation in risk, they will ignore the reverence, which they observed before the learned in normal conditions). For salvation from such great dangers, Islam instructs to avoid discussions and talks having an aggressive, hostile and eristic aspect, and even do not apply this way for proving the truth.

Stopping selfishness One, who wants to influence on the spirit and thoughts of others, should never insist them to accept the realities as "an idea belonging to him". Rather, in contrary, he shall try to express the realities absolutely and even as the idea of the other party. Pay attention! As we know everybody loves his ideas like his physical children, and the reason for love and interest in both cases is the same.

His ideas are considered as a part of him just like his children, and loving them forms a beam of self-love, which is the most rooted man's instinct. And in contrast, the thoughts of others are strange to man like the others' children, and naturally fail to attract his interest, and even sometimes they provoke his competition sense.
