What is Al-Quran?

Allah sent no messenger except and supported him with sensory miracles of the genus that the people of his time excelled in, so the challenge will be more powerful and more effective. 

These miracles are evidence of the truthfulness of his message, and it ends in its time and place, and thus it is an argument for those who witnessed it and saw it. 

The stick was the most prominent miracle of Moses - (peace be upon him) - and his book The Torah, and the rebirth of the dead with the God willing, and the most important miracles of Jesus - (peace be upon him) - his book The Gospel.

After the death of Moses - peace be upon him -  the features of the Torah were obscured, and God raised Jesus - peace be upon him - and the Gospel was corrupted after him, so we have more than 6 thousand different Gospels. And the matter did not stop there, with the passage of time, the Torah and Gospel texts that were originally distorted were unable to keep pace with developments and events, so the Jews and Christians intent on them from time to time with further revision and distortion.
