I can respect your posts (which reflect your belief) in-spite of being far from ours.

Any way when you say:

the Quran does not record Mohammed performing any miracles and Mohammed himself denied he was given powers to perform miracles.
Our Prophet Muhammad (Allah's blessing and peace be upon him) had many miracles and mentioned in Quran and hadiths. I do not know where "Mohammed himself denied he was given powers to perform miracles"?

1- Holy Quran is his miracle and still there are miracles are hidden between the verses of this holy book who enemies admire before friends.
2- The event of moon split:

In the name of Allah, the Entirely Merciful, the Especially Merciful
The Hour has come near, and the moon has split [in two]. (1) AlQamar

3-Mentioning his victories in holy Quran, Allah's promise to him to widespread his religion.
4-Muhammad (Allah's peace and blessing be upon him) knows many secrets and events.

Of course those happened by Allah's permission, the same to Jesus when Allah refers to his miracles in our Quran:

In the name of Allah, the Entirely Merciful, the Especially Merciful.
And [make him] a messenger to the Children of Israel, [who will say], 'Indeed I have come to you with a sign from your Lord in that I design for you from clay [that which is] like the form of a bird, then I breathe into it and it becomes a bird by permission of Allah. And I cure the blind and the leper, and I give life to the dead - by permission of Allah. And I inform you of what you eat and what you store in your houses. Indeed in that is a sign for you, if you are believers. (49)Al Umran


In addition to many other miracles in Quran and hadiths.

Peace to you
