All prophets including Muhammad showed miracles, I showed this in my Turkish article.

Every time a miracle was asked from them, no positive answer was given. Like the prophet Muhammad, they said, "We cannot perform miracles on our own." Many times, requests for miracles were denied:
Holy Quran 14:11 Their messengers said: "We are indeed human beings like you, but God will bestow His grace upon whom He pleases from His servants. And it is not up to us to bring you proof except with the permission of God. And in God the believers should place their trust"
13:38 AndWe have sent messengers before you and We have made for them mates and offspring. It was not for a messenger to come with any sign except with the permission of God; for each period there is a Book.
40:78 And We have sent messengers prior to you. Some of them We have told to you, and some We did not tell to you. And it was not given to any messenger that he should bring a sign except with the permission of God. So, when the judgment of God is issued, the matter is decided with the truth, and the followers of falsehood will be lost.
11:32 They said: "O Noah, you have argued with us, and continued arguing with us, so bring us what you promise us if you are of the truthful ones."
11:33 He said: "It is God who will bring it to you if He wishes; you will not have any escape."
11:34 "And my advice will not benefit you if I wanted to advise you and God wanted that you should go astray. He is your Lord, and to Him you will return."
