We don’t contact to this subject that in imam sadiq’s life, he goes up to the pulpit for guidance to the people and to give a lecture. and in imam’s age he couldn’t gives a lecture in manifest to the people because of the age’s condition.but after a lot of trying we could find two sermons of imam sadiq that one of them is long and the other one is short:


The first sermon is made from two parts. first it’s about prophet Mohammad’s descripthion,and the second one is about imam’s qualities and their descriptions that the first part’s translation is written here:
God is so kind and sympathetic to his creature that their bad works and their crimes don’t prevent him to don’t send Mohammad; their lovely and best prophet to their guidance.
Prophet Mohammad was born in the honorable and great family. and there isn’t any suspicious in his purity character.

And his behavior and characteristics is familiar by the world wises. He is a prophet that the God's other prophets announced his coming in their books and the Scientifics said a lot about his characteristics and philosophers were so careful to said about his accomplishments and his behavior's preferences. He was a well intended that never inclined to embarrassed. He was a man that there is nobody the same as him and nobody could reach to his position. He was the character that shame was manifest from his face and a prophetic behavior was evident in all his existence, his guidance and characteristics.
God's wish is that each nation should give good sense to the next generation about the prophet Mohammad (peace be upon him).
God's resolve and the world that the God creates is like that each nation gave glad tidings to its next nation about the new prophet and each Imam transfers this news to the next Imam.
There weren't any unclean less in his nature and in his marriages that he could right a way with them there wasn't any unclean less and
un truthfulness.
He grown up in of the best tribes, the greatest generation and the healthiest womb from Adam's creation till Abdullah's creation, his last father.
God chose him and was satisfied from him and granted him with a lot of knowledge and appointed him the best prophet for peoples whom were so depress.
God gave him the Quran, the most complete book that there are descriptions about every thing. This book is Arabic without any deviation for people for them to accept the Piety.
The Prophet Mohammad explained this book to people and with this book he interpreted the religion. He explained the things that the God orderd to do and duties and distinguished the life's frontier.
He disclosed the secrets that should have been disclosed to the people and opened the ways that were so important for people's guidance. So he started his teachings and listened to God's commands decisively and did all his responsibilities in the best way. He tried a lot in God's way and guidance of people to the deliverance he reminded people of the God and show them the right way and for measure this way appointed some signs, because he didn't want his companions deviat after him; so he was the kind leader and he still is.
In the second part of this sermon, Imam Sadiq says about Imams charactristis:
God, the most high, with his prophet destroyed all religious suspicious and show the right way in peoples existence; so each person that knows all the things about his leader or Imam he knowes all the things about the religion and understand Islam's beauty, because God put the perfect sign to the people of each age.
Imam constantly confirmed by God and the people could not reach to the God's satisfaction without Imam, and their prays will not pass to God unless they know about the Imam of their age.
Imam is omniscience about all problems that maybe happen in the different conditions and he is knowledgeable too about all old customs that always were in history.
God, the most high, always chose Imams for people from Hoseein's generation and make them known to people by themselves. God is so satisfied and so happy with their leadership and when one of Imams died the next Imam appointed by the God to the Leadership of people. There are clear signs that shows Imams are chosen by the God.
They know truthfulness, and all of them are moving to the God, invite people to the religion, and are guides by the creator.
The people will be religious with their invitation and the countries were shining with their existence. Because of their religion the prosperous effects increased. The God chose Imams for societies, life, and appointed them like bright torch in the darkness of ignorance. They are Islam's bases and knowledge keys.
These imams were the substitutes of prophets like Noah, Abraham, and Ismael's generation. Imams are divine and never commit any crime. Imam is free from Evil's trap and he is pure from any darkness and ignorance. You can not find any defect in the existence of Imam. At the end of his father's life he is appointed to guide people and by the knowledge granted to him by the God give happiness to the life people. So the helpless people awarded of religion by Imam. Those who follow their instructions became prosperous in two the worlds.
And those people who do not follow imam's instructions and do not accept their high position would be unlucky in the two worls.
