It is a reality that, in the legislative system of Islam, human nature, which is the same at all times and in all places, has been taken into consideration and positive answers have been given to natural human wants and needs. A careful study of Islamic precepts and programs reveals the fact that they have been so designed as to regulate all human instincts. For example, for the proper satisfaction of human sexual instincts, various simple plans and rules have been offered that properly satisfy and regulate this natural instinct at the same time that they prevent unrestrained sexual relations, so human societies may be immune from the corruption and decline that sexual freedom causes. The fundamental rules anti laws in Islam are meant not just for a particular time or a particular place needing modification and change as conditions change, they are compatible with all environments and all times and are capable of providing human beings with all the guidelines they need to live happily and prosperously and to find eternal salvation as well. In the Islamic programs and teachings concerning jihad, for instance, no emphasis is placed upon weaponry and tactics of the time of the Prophet, such as fighting with swords. Rather, Islam has given this general command concerning jihad: Strengthen your fighting abilities, mobilize your forces, and- acquire good arms and ammunition so you will be able to defend your vital rights against your enemies and overcome them.
This is a general all-embracing rule that is in accordance with all conditions of life and all sorts of progress made in technology. And thus this comprehensive rule can invariably give guidance on the questions concerning war in Islam, and the same is the case with other Islamic rules and instructions.
To the deadlocks and emergencies that occur in human life, either individual or social, the faith of Islam has offered laws such as 'the law of emergency', 'the law of not guilty', 'the law of no loss', 162 and the like, which present suitable solutions to all problems, however complicated they might be. Moreover, the Imams, the successors of the Holy Prophet of Islam, and religious leaders whom Muslims follow can offer decisive solutions to social deadlocks and problems. The programs and rules designed by Islam are far more extensive and elaborate than those presented by other schools of thought.
In Islam, all legal, economic, military, moral, and other issues and points have been presented and surveyed in the most elaborate and perfect manner. The Islamic theologians have so far compiled thousands of books on the fore-going subject for which the sources are the Holy Qur'an, the sayings of the Holy Prophet of Islam, and the teachings of the offspring of Prophet. Thus, taking into consideration these facts and proven realities, any knowledgeable person will admit that Islam is a perfect faith, capable of fulfilling human needs and of presenting solutions to all problems, and so there is no need for any other faith or any new school of thought.
