In The Name Of Allah, the Most Gracious, the Most Merciful
When Allah chose Muhammad (S.A.W.) for prophet- hood He appointed him to be the "Last Prophet". Our great Prophet-at Allah's order-from that very same initial invitation introduced himself as the 'Khatam' of the prophets, meaning, the last Prophet of Allah, and preached thus: "After me there will come no other prophet."
All of the people who, at the beginning of Islam, believed in Muhammad (S.A.W.), and became Muslim, knew that he was Allah's last Prophet. The Holy Qur'an, Allah's word and the Prophet's permanent miracle also introduces Hadhrat Muhammad as the last of the prophets, saying, “Muhammad is Allah's Prophet and the last of the prophets."
Therefore, we Muslims, who know the Qur'an as the Book of Allah, and Hadhrat Muhammad (S.A.W.) as the last of Allah's prophets, have no doubt or hesitation whatsoever, about this matter. The Islamic codes of behavior are such that to an exact and complete degree, the human being can find truth there, at any time or in any place, thus achieving prosperity, perfection and nearness to Allah-upon whom all human beings, in all times depend, has given carefully adjusted, and exact codes of behavior in the Qur'an, in order to fulfill the needs of human beings, and guide them.
In this way, however, knowledgeable and learned that a human being becomes, again it is the Qur'an-the word of Allah and divine guidance-that he stands in need of, in the same way that God's creation in all times, and always, need sunshine, water and air.
The Islamic codes of behavior are in the Qur'an.
The Qur'an is the last heavenly book, and the immortal book of the religion of Islam, which Allah protected with the self-sacrifice of the striving Muslims, so that it could come down to us. This great book, is the best and most perfect plan and guidance for human beings. In this manner, the Great Allah, has introduced Islam as the last heavenly religion, and our Prophet as the last Messenger. We Muslims, must, by following our own leader, which is the Qur'an make great efforts and live victoriously, so that in the Hereafter, we can also find prosperity.
