Short answer
Yes. Muslims believe Allah supported His prophets with miracles (mu'jizat): Musa's staff becoming a snake, Isa healing the blind and giving life to the dead by Allah's permission, and the moon splitting for the Prophet Muhammad ﷺ, among many others. The Prophet's greatest miracle is the Quran itself, which still stands today.
Sunni creed affirms the miracles of the prophets as real events Allah creates, outside the normal course of nature, to prove a prophet's truth. Wonders given to righteous people who are not prophets are called karamat and are also affirmed; magic and trickery are something else.
The four schools agree on this.
Explanation
A mu'jizah is something that breaks the normal pattern of nature, done by Allah at the hands of a prophet who claims prophethood and challenges people to match it. The Quran is full of them. Ibrahim was thrown into a fire that Allah made cool and safe. Musa's staff became a snake and parted the sea. Isa said: "I cure the blind and the leper, and I give life to the dead, by permission of Allah" (3:49).
The Prophet Muhammad ﷺ also had many. The Quran says "the moon has split [in two]" (54:1), and the Companions reported seeing it. Sahih hadith describe water flowing from between his fingers, a little food feeding a whole army, and a tree trunk crying when he left it for the minbar. The Night Journey to Jerusalem and the ascension through the heavens was another.
Yet the Prophet ﷺ said every prophet was given signs that made people believe, and what he was given was revelation, the Quran, and he hoped to have the most followers on the Day of Judgement. Earlier miracles were seen by those present; the Quran can still be read and tested. Allah challenges all of mankind and jinn to produce its like (17:88).
Some people ask how miracles fit with science. The laws of nature are Allah's habits in creation; the One who made them can suspend them when He wills. Read more on the miracles of the Quran, Isra and Miraj and karamat of the awliya.
The evidence
Quran, Surah Al-Qamar 54:1
بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ ٱقْتَرَبَتِ ٱلسَّاعَةُ وَٱنشَقَّ ٱلْقَمَرُ ﴿١﴾
The Hour has come near, and the moon has split [in two].
Records the splitting of the moon.
Quran, Surah Aal-i-Imraan 3:49
وَرَسُولًا إِلَىٰ بَنِىٓ إِسْرَٰٓءِيلَ أَنِّى قَدْ جِئْتُكُم بِـَٔايَةٍۢ مِّن رَّبِّكُمْ ۖ أَنِّىٓ أَخْلُقُ لَكُم مِّنَ ٱلطِّينِ كَهَيْـَٔةِ ٱلطَّيْرِ فَأَنفُخُ فِيهِ فَيَكُونُ طَيْرًۢا بِإِذْنِ ٱللَّهِ ۖ وَأُبْرِئُ ٱلْأَكْمَهَ وَٱلْأَبْرَصَ وَأُحْىِ ٱلْمَوْتَىٰ بِإِذْنِ ٱللَّهِ ۖ وَأُنَبِّئُكُم بِمَا تَأْكُلُونَ وَمَا تَدَّخِرُونَ فِى بُيُوتِكُمْ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَةًۭ لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ ﴿٤٩﴾
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.
Lists miracles of Isa, done by Allah's permission.
Quran, Surah Al-Israa 17:88
قُل لَّئِنِ ٱجْتَمَعَتِ ٱلْإِنسُ وَٱلْجِنُّ عَلَىٰٓ أَن يَأْتُوا۟ بِمِثْلِ هَٰذَا ٱلْقُرْءَانِ لَا يَأْتُونَ بِمِثْلِهِۦ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍۢ ظَهِيرًۭا ﴿٨٨﴾
Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants."
The Quran's challenge, the lasting miracle.
Sahih al-Bukhari 4981
Sahih... مَا مِنَ الأَنْبِيَاءِ نَبِيٌّ إِلاَّ أُعْطِيَ مَا مِثْلُهُ آمَنَ عَلَيْهِ الْبَشَرُ ...
"There was no prophet except that he was given signs because of which people believed."
Shows every prophet had miracles, and that the Quran is the Prophet's greatest.
Where the ruling is recorded
- al-Aqa'id al-Nasafiyya with Sharh al-Taftazani, Section on prophethood and miracles. Defines the miracle and affirms the miracles of the Prophet ﷺ, chief among them the Quran.
- al-Fiqh al-Akbar (Imam Abu Hanifa), Section on the signs of the prophets and the karamat of the awliya. Affirms both as true.
