After God empowered Muslims to enter Mecca, Islam became the prevailing power and was spread by use of fear. This was particularly evident in the tribe of Quraysh, who had responded to the Prophet Muhammad’s new message of Islam with unrelenting persecution, eventually putting its resources in the service of the ever growing new religion. The Prophet then saw it preferable to contact neighbouring kings and rulers, including the two kings of Oman, Jaiffar and Abd, sons of Al Julanda, through peaceful means. History books tell us that the prophet had sent messages to the people of Oman, including a letter carried by military escort from Amr Inn Al Aas to Jaiffar and Abd, sons of Al Julanda, in which he wrote: ‘In the name of God the Merciful and the Compassionate, from Muhammad bin Abdullah to Jaiffar and Abd, sons of Al Julanda, peace be on those who choose the right path. Embrace Islam, and you shall be safe. I am God’s messenger to all humanity, here to alert all those alive that non believers are condemned. If you submit to Islam, you will remain kings, but if you abstain, your rule will be removed and my horses will enter your arena to prove my prophecy’.
