Existence's sun of eight shining star from Imamat cradle , Hazrat Ali , the son of Moses (p.b.u.h.) who is famous to Reza became radiant from province horizon , on Friday , eleventh Dhu'l-adoh in 148 Hegira-lunar in Medina.

Imam Reza (p.b.u.h.) had high knowledge and degrees in addition to human and moral exalted excellences , like his own great father and his dear ancestor , Hazrat Mohammad.

Eighth Imam was contemporary with four Abasi caliphs in his blessed life time that Mamon was the last one of them.

Mamon's time was the time of mental motion and scientific development , because of his interest in knowledge.

Great scientists from different nations moved to caliphate center , because their country was under the Islam influence and domination and caliph honored their arrival and respect them so much.

Because of scientist's encouragement , little by little , all people get interested in knowledge and so many scientific arguments meetings were held by the government and honor person ( Imam Reza (p.b.u.h.)) was in the head of these meetings.

In one of these meetings , caliph invited thirty-three thousand people of different religions scientists from across the Islamic countries.

Omran Sabi , one of the people who debated with Imam that was the boss of the Sabaism religion. One of the Omran's question from Imam was : God is in creation or the creation is in God ?

( Is God in our around objects and people or our around objects and people are the signs of God ? )

Imam (p.b.u.h.) said :" Omran ! the God is more greater to speak about him like this ; neither God is creation nor creation is in him. I ask a question which includes your answer. Have you ever seen the mirror ? Are you in mirror or mirror is in you ?

In fact , none of you are in each other. Omran ! How do you see yourself in mirror ?" Omran said : by the light and ray which are between me and mirror.

Imam (p.b.u.h.) asked :" Is the light of what you see in the mirror more than object's reality in outside."

Omran said : yes. Imam (p.b.u.h.) said :" well ! show us where that extra light is !" Omran got amazed and fell down his head and couldn't answer. Imam Reza (p.b.u.h.) said :" you didn't answer but I'll tell you the fact. The light moves without being in you and in mirror and it guides you to mirror and guides mirror to you and also guides both ( you and mirror ) to itself."

In mentioned version , Imam (p.b.u.h.) pronounce the argument about God's manifestation on creatures and imagines the world as God manifestation's mirror on creatures and says :" exalted God is sheer light that has led all creatures to himself while he is not in anything and nothing is in him either even the fact of all creatures appear by him and they become meaningful."

Imam's great responsibility was to answer all scientific problems which were not analyzed in debates and argumentations.

in fact , proved his own scientific power and showed Imamat position to people in the world by means of science.

In the time of Imam Reza scientific problems and questions were pronounced based on medicine , natural science , mathematics , astrology , divine philosophy , unification and speech because of lack of people's information in that time , so answering to people was so difficult and sensitive.

But Imam stated convincing and efficient answers about all problems by his own unique and divine scientific power as the greatest scientist at that time confess that Imam Reza (p.b.u.h.) is the most greatest scientific champion in the world and no human is able to have a scientific competition with him.
