And education cannot be considered a miracle for the Messenger, or come with supernatural acts like the splitting of the moon and the stars, and the appearance of light, and the splitting of the heavens, which are impossible for anyone other than the One who created them and revealed them in accordance with his claim. And the agreement between the miracle and the claim is perceptible, and there is no way to deny perceptible things.

When a miracle appears at the hands of a prophet in agreement with his claim, it confirms his truthfulness, just as the circumstances that arise necessitate it. For example, if we saw a man whose color had changed and his joints were trembling, and he informed us that he had seen a lion that frightened him, his change would stand for us as a definitive necessity for his truthfulness in what we witnessed of his changing color, the trembling of his joints, and his fear that it was due to seeing the lion.

What the Prophet brought, accompanied by a miracle, we cannot deny, nor do we have a choice in it. It is a matter known by necessity. An example of this in the perceptible world is if a king of the kings of this world, of great prestige and importance, whose command is obeyed, sent a messenger to his subjects with a letter containing his command and his message, and they knew that this was possible for him and that he could assign them whatever he wished. And with him was his seal, which could only be attributed to him and could not exist with anyone else, and he would only give it as a sign and proof of the truthfulness of his messenger. And these three things concerning this seal were known to them and definitively established as proof of his truthfulness. When the letter reached them and they knew what was in it, they said to him: The commands are from the king. And we do not know your truthfulness except by a sign that indicates it. So he brought them the seal. When they saw it, they knew it and confirmed that it was his seal, which he only revealed as a sign of the truthfulness of his messenger. Then their assignment was established, their confirmation was assured, and their certainty was valid. The example of the king is an example of God, the Most High, and the highest example belongs to Him. The example of the king's messenger is an example of the Messenger, peace be upon him. The example of the king's letter is an example of the message. The example of the seal is an example of the miracle. So the Messenger's truthfulness is based on the appearance of the seal, and the validity of the letter is based on the Messenger's truthfulness. If the validity of the letter is known, then it is obligatory to believe what is in it and to obey what it contains of commands and prohibitions.

The truth is that this example involves obtaining knowledge by convention, not by necessity, which the Mahdi used as an example to prove it.
