Seeing as how sometimes people go to one extreme and think that to be of good character means that a person must give up his rights in the face of his enemy, the Prophet (S) continued his speech by saying that although interaction with a true believer and indeed his character is sweeter than honey (very kind and loving), but at the same time he is not a push over. Rather, in the face of his enemies, he is harsher and harder than a rock (meaning that he does not give in).
”(The true believer) is firmer and stronger than iron and more powerful than a mountain.” As we know, a mountain and even iron can be molded and cut through however a true believer can never be cut through, molded or changed. The true believer must be just as 'Ali (as) was.
However there are some people who bring up the excuse that since by nature, Imam 'Ali (as) was a very joking person, thus, he was not able to be the leader of a society - however at the same time, we see that he was also powerful and harsh with others.
Of course in those areas where the Islamic laws give permission, a person must not be harsh and unsympathetic and it has been mentioned that the person who is harsh with others in this world will be judged with harshness by Allah (SwT) on the Day of Judgement. The twenty-fifth characteristic of a true believer is that he does not expose the secrets which others confide in him. What does it truly mean that one does not expose the secrets of others??
We know that during the course of one's life, all of us have secrets which we do not like others to know, because if they were to be known, then this would make life very difficult. Thus, if a person was to relate thess secrets to other people and tell them that, “Whatever has been mentioned in this gathering is a trust that you must keep and no one else must know these secrets”, then this must be obeyed.
