ISLAMIC BELIEF, DOCTRINE AND PRACTICES
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', 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.
THE END OF PROPHECY WITH THE PROPHET
The comprehensiveness of the rules and precepts of Islam and the end of prophecy with the Holy Prophet of Islam have been clearly expressed in the Qur'an: `And the word of your Lord has been accomplished truly. and justly; there is none who can change His words, and He is the Hearing, the Knowing' (6:115).
'Muhammad is not the father of any of your men, but he is the Messenger of God and the Last of all Prophets, and God is cognizant of all things' (33:40).
In the Arabic language, wherever the word `khatam' is attached to a word, it conveys the meaning of `the last' and in this verse it refers to `the last of the prophets'. Nabi means any type of divine messenger.
Obviously, the word messenger can be applied to all prophets so by saying that Muhammad is the last of all prophets, God means that he is the last of all messengers and that after him there will come no prophet, nor any messenger from God, nor any person with a new holy book.
`Surely this Qur'an guides to that which is most upright and gives the good news to the believers who do good that they shall have a great reward (17:9).
Therefore, human beings have no need for any other prophet, any other rules and regulations, or any other school of thought because all they need is to be found in the Qur'an.
