Oh, so your prophet performed a few miracles?

So anyone telling you, "our prophet performed miracles, and many people witnessed it"? Well, if they are, ask them if G-d spoke to millions of people when creating their religion or are they just relying on the fact that one man says that G-d spoke to him.

Well they might have very well performed miracles! After all read the Torah (Deuteronomy 13:1-5):

13:1 Everything I command you that you shall be careful to do it. You shall neither add to it, nor subtract from it.
13:2 If there will arise among you a prophet, or a dreamer of a dream, and he gives you a sign or a wonder,
13:3 and the sign or the wonder of which he spoke to you happens, [and he] says, "Let us go after other gods which you have not known, and let us worship them,"
13:4 you shall not heed the words of that prophet, or that dreamer of a dream; for the L-rd, your G-d, is testing you, to know whether you really love the L-rd, your G-d, with all your heart and with all your soul.
13:5 You shall follow the L-rd, your G-d, fear Him, keep His commandments, heed His voice, worship Him, and cleave to Him.

So let us see, a guy comes along and says that his "prophet" named Jesus or Mohammad comes along and in violation of the verse 1, subtracts from the law, saying we no longer should follow the Torah, but instead follow their books, and to show "proof" because they perform a "miracle".

After reading the above verse, can you do anything but laugh at them? I mean, G-d describes it at a very simple level to us!
