QURAN N SUNNAH R OUR POWERS!!!

Islam is an Arabic word that means "submission". So, Islam in its universal sense is full submission to ALLAH (Arabic word for God), the one and only one God. In this understanding, ALLAH message to Prophet Mohamed (PEACE BE UPON HIM) is not isolated or different from God message to all His prophets including Noah, Abraham, Ismael, Isac, Jacob, Joseph, Moses, David, Solomon, Jesus (PEACE BE UPON THEM), until his last prophet Mohamed (peace upon them all) but it is a continuation to previous God messages and previous prophet missions. The basic principle of all ALLAH messages is to call people to worship ALLAH, the one and only one God and to call mankind to full submission to ALLAH, the one and only one God. So, sure Islam, in its universal sense, is true religion of God.
