Peace through submission to Allah
Islam is the religion of truth. It is the embodiment of the code of life, which Allah, the Creator and Lord of the Universe, has revealed for the guidance of mankind. The meaning of the word of Islam is "peace" and this signifies that one can achieve real peace of body and mind only through submission and obedience to Allah. Such a life of obedience brings peace of the heart and establishes real peace in society.
Allah, the Exalted, says: "Those who believed (in the Oneness of Allah) and whose hearts find rest in there memberance of Allah: verily, in the remembrance of Allah do hearts find rest. Those who believed (in the Oneness of Allah) and work righteousness, (all kinds of happiness or name of a tree in Paradise) is for them, and a beautiful place of (final) return." Qur'an 13:28-29
Islam is a complete way of life, catering to all the fields of human existence. Islam provides guidance for all aspects of life - individual and social, material and moral, economic and political, legal and cultural, national and international. The Qur'an enjoins man to enter the fold of Islam without any reservation and to follow God's guidance in all fields of life.
