In matters of criticism or expression of differences, the right approach is for people to end unnecessary sensitivity to it instead of attempting to put an end to criticism and differences. This is the demand of Islam as well as of nature. According to the hadith it is a virtue on the part of believers, to accept the truth without any reservation when it is presented to them. That is to say, a believer is one who has the ability in the perfect sense of the word to accept the truth. Whenever truth is brought before him, whenever his faults are pointed out to him, no complex comes in the way of his accepting of the truth. This quality is present to the maximum degree in one who is ready and waiting to accept the truth when it is brought before him. Eager for his own improvement, he accepts the truth with pleasure. This keenness for self--reform through acceptance of the truth is perfectly expressed in the words of 'Umar bin al-Khattab: "May God bless the man who sends me gifts of my own shortcomings." It is a fact that acknowledgment of truth is worship, nay; it is the greatest form of worship. It is an act for which man has to make the greatest sacrifice. What makes it such a great sacrifice is that it involves the setting aside of one's prestige. It amounts to the sacrifice of one's ego. But that is the occasion when man assures his entry into heaven. When does one find the opportunity for this great form of worship and this great good fortune? This opportunity comes one's way only when there is full freedom of expression. When one can criticize another with impunity. When such an atmosphere prevails in a society, which permits the speaker to air his views freely and the listener may freely appreciate what is being said. Just as a mosque is the right place for the performance of prayer in congregation, similarly freedom of expression is the right atmosphere in which to foster the great virtues of expressing the truth and acceptance of the truth.
