BUKHARI'S CRITERIA FOR ESTABLISHING WHICH HADITH NARRATIONS ARE NOT GENUINE:
When dealing with sahih hadith narrations, THE BURDEN OF PROOF IS ALWAYS ON THE PERSON WHO CLAIMS A CERTAIN NARRATION [OR HADITH] IS NOT AUTHENTIC AND TO PROVIDE EVIDENCE FOR WHY IT IS CONSIDER NOT TO BE AUTHENTIC.
IMAM BUKHARI came up with three criteria which he used to determine whether or not a narration was sahih or not. His third criteria is mat'n, i.e. THE CONTENT OF A NARRATION MUST NOT BE IN CONTRADICTION WITH THE QUR'AN, which is important to remember for purposes of the analysis set forth below. The only exception to this rule is the narrations regarded by scholars to be Qudsi (narrations which contain non-Qur'anic words from Allah).
HADITH EVIDENCE THAT MOHAMMAD DID NOT PERFORM ANY MIRACLE:
When challenged by skeptics, the hadith record that MUHAMMAD DENIED BEING ABLE TO PERFORM ANY MIRACLES. He admitted that although other prophets before him were given the power of performing miracles, HIS ONLY [ALLEGED] MIRACLE WAS THE QUR'AN, as stated in Quran 9:92 as follows:
(Sahih Bukhari 9:92:379)Narrated Abu Huraira: The Prophet said, "There was no prophet among the prophets but was given miracles because of which people had security or had belief, but what I was given was the Divine Inspiration which Allah revealed to me. So I hope that my followers will be more than those of any other prophet on the Day of Resurrection."
QUR'ANIC EVIDENCE THAT MOHAMMAD DID NOT PERFORM ANY MIRACLE:
Reaffirming the previous hadith that Mohammads only supposed miracle is the Quran, in the following Quranic verse Muhammad is acknowledging that other prophets before him came with miracles or clear signs but still people rejected them, highlighting the futility of miracles as the proof of his [Mohammads] revelation:
(Qur'an 3:138)They (also) said: "Allah took our promise not to believe in an messenger unless He showed us a sacrifice consumed by Fire (From heaven)." Say: "There came to you messengers before me, with clear Signs and even with what ye ask for: why then did ye slay them, if ye speak the truth?" if you are truthful?
When unbelievers asked Muhammad to perform a miracle so that they too could believe that he is a prophet, all they heard from Mohammad in response is:
(Qur'an 17:90)They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth,
And he would reply:
(Qur'an 17:93)Say: "Glory to my Lord! Am I aught but a man,- a messenger?"
In other words, Mohammad was unable to perform a single miracle, therefore people doubted Muhammad because they saw nothing extraordinary or miraculous in him:
(Qur'an 17:94)And naught prevented mankind from believing when the guidance came unto them save that they said: Hath Allah sent a mortal as (His) messenger?
(Qur'an 25:7-8)And they say: "What sort of a messenger is this, who eats food, and walks through the streets? Why has not an angel been sent down to him to give admonition with him? "Or (Why) has not a treasure been bestowed on him, or why has he (not) a garden for enjoyment?" The wicked say: "Ye follow none other than a man bewitched."
So according to Quran 27:7-8, the Qurans only excuse as to why Mohammad could not perform a miracle is that those who do not see a miracle and therefore do not believe are automatically deemed to be wicked. Yet, Muhammad kept telling unbelievers that he is just an ordinary man, not an angel meaning people should not expect miracles from him!
