Question 7: How is it appropriate for a prophet from Uli Al-Azem , who is Abraham pbuh, to say that the planet, or moon, or sun is his Lord?
Answer: Only a deluded person would assume that these words came from Abraham pbuh in the world of Shahada, meaning this worldly life, even though Abraham perhaps repeated it in this worldly life to reproach his people who worship these planets, or the spirits which move these planets.
he sun is the Messenger of Allah pbuhap, the moon is Imam Ali pbuh , and the planet is Imam Al-Mahdi pbuh. 
The sun, moon, and planet in the Kingdom of Heaven were the manifestation of Allah in the creation. For this reason, they were made similar to Abraham pbuh and each of these three is a manifestation to its own extent. And Muhammad, Ali and Al-Qaim pbut, specifically, are the complete manifestation of Allah in the creation in this world. This is because not only are they dispatched, but they are dispatchers as well.
Is there a planet other than the planet Earth where people exist, or any other kind to whom Prophets and Messengers and Muhammad sawas. and Imams a.s were sent?
