Upon your heart that you may be of the warners, In plain Arabic language.

Upon your heart…” (26:193-194) And did not say: “upon you”, which indicates the comprehensiveness of Quran from the side of the Holy Prophet (S) and also whatever he received from the soul was his noble self without his conscious perception having any interference in it. Therefore, he hears whatever is revealed to him without the intervention of his eyes and ears.

Because if his seeing and hearing had been through the apparent eyes and ears, everything he heard would be shared by others; that is whatever he sees, people also see it, while the fact is that traditional reports have refuted this meaning absolutely.[^2] That is why, the knowledge of prophets, which is obtained through revelation, is not like obtained knowledge learned through perception and human thinking, on the contrary it is of a higher type, whose essence is not clear to us.

It is a type of secret and hidden understanding and errors and doubts cannot enter it. From some verses, it is learnt that revelation takes place in one of the following three ways: First method: Almighty Allah reveals matters directly on the heart of the prophet. Second method: Matters are sent down to another place and the prophet obtains from there, like in the case of the conversation of Prophet Musa (a.s.) at Mount Tur through the tree.
