Sheikh Ahmed bin Hamad Al Khalily, the grand mufti of Oman, has said that there are two reasons for the spread of Islam. First, there is the internal reason that has something to do with its principles and articles of faith, including its morals and values to humanity, as contained in Qur`an and the Prophet’s Sunnah. He said as for the external reason, it is represented by the very people who embraced Islam and its message.
