Every Prophet had a miracle which he showed to his people and challenged them with. some of the prophets even had more than one sign as a definite proof that they were sent by Allah ; Challenging their nations to bring anything similar to it if they denied it.

However , One such miraculous sign shall remain, complete and prserved with the command of Allah , until the Day of Resurrection. this miracle is the inimitable Quran , the everlasting book of Allah given to Prophet muhammad ( Peace and Blessings be Upon Him ) . Any one who lives after the Death of this Prophet of Mercy will be able to see it , read it and realize for themselves the truth that it contains.
