یَابْنَ الْغَطارِفَةِ الْأَنْجَبِینَ أنتَ اَمانٌ لِأَهلِ اِلأرضِ....

Imamate as the terms of word means leadership and Guardianship of society, even God, in surah tobe verse 12 said that "فقاتلوا آئمة الکفر ... That s mean that allah introduce leaders of disbelief as imams of disbelief.

Thus Imam as the terms of word means leader,so when we say that Imam Khomeini (PBUH) and Imam Khamenei, it is never meant that these loved ones are innocent, no, the innocent are only fourteen innocents

For us, because of the position of leadership, we called them “Imam'that has raised doubts for some people and criticize why you called them Imam! Because God himself  in Qur'an even called the leaders of disbelief, imam

Imamate as a expression means, the innocent person who is chosen by Allah Almighty for the succession prophet mohammad (pbuh) and even after the Imams, the one who comes from generation to generation, to lead and control the community.

But it is good to know that, from the Sunni s point of view, Imamate isn’t only the divine position but also is the worldly position and the Imam is responsible for worldly things and manage the worldly works and being the ruler of the people. That s mean that they don’t appreciate and devote attention to the people's future and the work of leading people towards the futurity, and now may be chosen on the basis of voting or on the basis of the council or even on the basis of the coup or on the basis of will of the previous caliph

imamate is the divine and heavenly  position which is choosen by allah for the purpose of explaining the teachings of religion. The choice of Imam is not in the hands of the people; people do not have the duty to dismiss and install the Imam, because the choice of Imam is with Allah Almighty.

Why do we need Imam?that s clearand all of you know the famous hadith of the Prophet (pbuh) the hadith of Thaqalain becaus the Quran is immortal until the resurrection Therefore, until the uprising of the Day of Resurrection, one has to be beside of the Qur'an, in order to interpret the Qur'an and the instructions of the Qur'an,one who leads the people towards God. , Who, after the Prophet (pbuh), is responsible for guiding the people, both the appearance and inner guidance, as well as the leadership of the community, to form a government, keep the manner of Prophet, cultivate the soul of people.

Just now what traits should Imam have? The Imam should certainly have many moral, material, and spiritual qualities, but two important characteristics of Imam is the knowledge and infallibility of Imam.

 imam require science as well as the type of divine and theological science Why? Because it has to interpret the Qur'anic verses, it is necessary to fulfill the divine rules in such a way that it is not at all wrong, and it is completely correct, it is the responsibility of someone who connect to divine knowledge.

Amir al-Muminin (PBUH) said that  Imam is the most aware person about the lawful and forbidden instruction of allah and his various rules and everything that is needed by the people.

 The Hadith is in the volume of al-Hikma-i 1, p. 861
