You are relying on a bad translation. From the book comes clear signs and the other (things that come from it) are ambiguities. The clear signs are the original book.
Where does it say "from the book comes"?
When looking at this Hadith, it is clear that, the Book is divided into two types of verses:
- عيون أخبار الرضا (ع): أبي، عن علي، عن أبيه، عن حيون مولى الرضا، عن الرضا عليه السلام قال:
من
رد متشابه القرآن إلى محكمه هدي إلى صراط مستقيم، ثم قال عليه السلام: إن في أخبارنا متشابها كمتشابه القرآن، ومحكما كمحكم القرآن، فردوا متشابهها إلى محكمها، ولا تتبعوا متشابهها دون محكمها فتضلوا.
Uyūn Akhbār al-Riḍā (عليه السلام): From my father, from ‘Alī, from his father, from Ḥayyūn, the servant of al-Riḍā, from al-Riḍā (عليه السلام), who said: "Whoever refers the
ambiguous of the Quran to its clear is guided to the straight path." Then he (عليه السلام) said: "Indeed, in our narrations, there are ambiguous ones like the ambiguous parts of the Quran, and clear ones like the clear parts of the Quran. So refer the ambiguous ones to the clear ones, and do not follow the ambiguous ones without referring to the clear ones, lest you go astray."
For example, consider what Quran says;
"Every soul will taste death"
There is no ambiguity in this verse to anyone. It means the same to a disbeliever, to a Baha'i, to a Christian, to a Sunni, to a Shia.
This is Muhkam. It is not like, those who have diseased hearts, will get mislead and cause Fitna, and they do not know how to interpret it, and only God and infallible Imams know its interpretation.
Or consiser this verse:
"O my dear son! Establish prayer, encourage what is good and forbid what is evil, and endure patiently whatever befalls you. Surely this is a resolve to aspire to.." Lighman 17
This is a clear verse to anyone. To Abu Bakr, to Saddam, to Hassan Nasrallah, to me, and to yourself, it means the same. There is nothing ambiguous in this verse. And those whose heart have a disease, would not cause Fitna, or discord.
Such verses are not Mutishabihat to anyone, no matter how sick someone is.
These are Muhkammat.
Or here is a better example:
"....And lower your wing to the believers" 15:88
This verse is clear to anyone. No body would say, it means the Prophet actually have physical wing. Everyone, knows it is a metaphor, an analogy. Regardless it is Umar, Abubakr, Ali, you, Khamenei or an atheist, they all agree, this wing, is not physical. It is not like this verse becomes Mutishabih to those have a disease of heart.
