The messenger of Allah ( peace be upon him ) used different
methods to spread this religion and to convey it to all people
altogether.
One of these methods (ways) is sending messages to kings and
princes to make the invitationto Islam reach ( acc
ess to ) all parts of
the world.
Al-hudaibiya treaty ( reconciliation ) gave a chance ( an
opportunity) to expand (widen ) the range of the invitation to Islam
inside and outside of the Island of kings and the princes took place.
No doubt , the massager of the messenger of Allah (peace be
upon him) to the kings of the neighboring countries are a practical
expression of the internationality ( universality ) of the Islamic
message.
