The contemporary unity address in the area of the Ummah is faced with a number of serious challenges, some of which are:First: The bad consequences of the state of dissension and discord, and the policies of discrimination, the conflicts of differences and violent seditions, for we see that in the actual state of the political and social systems or regimes of most of our Islamic states do not establish justice and equality among their citizens according to the teachings of the Islamic Shari‘ah, or the conception of citizenship, or charters of the human rights. Thus ,there is discrimination between the citizens in rights and the chances of taking part in power, government, and wealth, because of their difference of their ethnical and sectarian relationship or belonging This, of course, has led to the eruption or waging of bloody wars in some of the Islamic countries, as it has happened in the south of Sudan, and Darfur (in W.Sudan), in the eastern part of Sudan, in the north of lraq, and in Eastern Turkey.Some of the religious minorities, whether a Sunnite sect in a Shi‘i surroundings, or a Shi‘i section in a Sunnite surroundings, complain about the policies of discrimination which make up the grounds for seditions and dissension, and create situations of conflicts, and disturbance.The product of such disorder in many situations will weaken the credibility of the unity address in the arena of the Ummah masses, and it will turn in the sight of those burned by the fire of discrimination and dispossession into mere wide title and bright motto.Secondly: The wide spreading and publishing of the address of mobilization and sectarian encouragement, which has not become mere a sermon or a talk in a mosque or Husayniyyah, nor a mere published book, but it has become mass media which go across the continents and on the sattelite channels, the websites of computer, and the mobile-phone services. Certainly, the producers of the media of sectarian encouragement compete with one another in kindling and stirring up the sensations, and arousing the hostility, enmity, rancour and hatred, so as to win a wider area of spectators, viewers, and recipients. They search, in the depth of history for the events of sectarian difference and variance of sectarian clashes and conflicts, and investigate the places of insult, and mischief in the books of old tradition, magnifying what is judged here and there, or rather fabricating events which have never occurred.This kind of sectarian address has become the highest sound, for it has been meant to arouse the feelings and sensations amongst the public. It has mostly depended on raising the violent seditions and renewed provoked passions. As a matter of fact, it has encircled the address of unity and coexistence, and fill it up with many fears and marks of questioning, among most of the environments of the masses of the Ummah. Rather, the effect of the sectarian address has extended and infilterated among some of the pioneers of the address of unity, and the leaders of moderation and temperateness in the Ummah, under the justification of refuting the objection and interaction of sectarian attitudes of the other party.Hence, this is the most regrettable affair, for it forms harmful decline and damage to the efforts of unity and taqarub (raprochement), besides it presents the best award and gains to the callers for sedition, dissension ad discord.Thirdly: the weakness of the response of the unity address to the necessaries of revival and development. Moreover most of it suffers stagnation, and inactivity in the contents which it adopts, and the styles and modes it employs, and at the level of activity and the credibility of effectiveness.This humble paper attempts to turn the attention to the necessity of renovation and development in the unity address, by means of raising a number of fruitful questions, notes and notices.
