The whole Quran is in the dot under the letter ب (Ba) and Ali is the dot

Question 6: What is the meaning of “the whole Quran is in the dot under the letter ب (Ba), and Ali pbuh is the dot”?

Answer: The shape of the [Arabic] letter ب (Ba) is a container which has been filled and is now overflowing upon others, and its content is drip- ping from underneath, while the shape of the letter ن (Noon) is a con- tainer receiving from above, and knowledge is dripping into it from its master.

Why did Abraham pbuh see only a planet, a moon, and a sun?

he sun is the Messenger of Allah pbuhap, the moon is Imam Ali pbuh [1], and the planet is Imam Al-Mahdi pbuh. [2]
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.
