the word Islam in Arabic comes from the word Salam, the word Salam means peace, that the word Islam means: make peace,
so, the word Islam means that the Muslim must make peace between him and his God and make peace between him and the others according to God's orders.
The explanation of the religion:
Islam is the religion of Muslims, based upon the teachings of Muhammed during the 7th century, and the second largest of the world's religions in number of believers.
Islam is a "religious system of belief revealed by Muhammad", the last Prophet of Allah (the one and true God). From the Arabic meaning "surrender", Islam is centered on the sacred scripture of the Qu'ran (Koran). The religious obligations of all Muslims are summed up in the Five Pillars of Islam, which include belief in God and his Prophet and obligations of prayer, charity, pilgrimage, and fasting. The laws of Islam cover all aspects of daily life and are codified in the Law, or Shari'ah.
The majority of Muslims belong to one of two major denominations, the Sunni and Shi'a. The term Shi'a usually refers to the largest subgroup within the Shi'a (known as "Twelvers" or Ithnā'ashariyyah' ) who share many of the practices of the Sunni. The groups originally split over the succession of Muhammad and now disagree mainly over the application of the Hadith, the narratives of Muhammad.
