Muhammad's Only Miracle was Quran

[Quran 10:20] They say, "How come no miracle came down to him from his Lord?" Say, "The future belongs to GOD; so wait, and I am waiting along with you."

(٢٠) وَيَقُولُونَ لَوْلَا أُنْزِلَ عَلَيْهِ آيَةٌ مِنْ رَبِّهِ فَقُلْ إِنَّمَا الْغَيْبُ لِلَّهِ فَانْتَظِرُوا إِنِّي مَعَكُمْ مِنَ الْمُنْتَظِرِينَ

[Quran 17:59] What stopped us from sending the miracles is that the previous generations have rejected them. For example, we showed Thamûd the camel, a profound (miracle), but they transgressed against it. We sent the miracles only to instill reverence.

(٥٩) وَمَا مَنَعَنَا أَنْ نُرْسِلَ بِالْآيَاتِ إِلَّا أَنْ كَذَّبَ بِهَا الْأَوَّلُونَ وَآتَيْنَا ثَمُودَ النَّاقَةَ مُبْصِرَةً فَظَلَمُوا بِهَا وَمَا نُرْسِلُ بِالْآيَاتِ إِلَّا تَخْوِيفًا

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، حَدَّثَنَا سَعِيدٌ الْمَقْبُرِيُّ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ مَا مِنَ الأَنْبِيَاءِ نَبِيٌّ إِلاَّ أُعْطِيَ مَا مِثْلُهُ آمَنَ عَلَيْهِ الْبَشَرُ، وَإِنَّمَا كَانَ الَّذِي أُوتِيتُ وَحْيًا أَوْحَاهُ اللَّهُ إِلَىَّ فَأَرْجُو أَنْ أَكُونَ أَكْثَرَهُمْ تَابِعًا يَوْمَ الْقِيَامَةِ ‏"‏‏.‏

Narrated Abu Huraira: The Prophet (ﷺ) said, "Every Prophet was given miracles because of which people believed, but only that which I was given was Divine Inspiration which Allah has revealed to me. So I hope that my followers will outnumber the followers of the other Prophets on the Day of Resurrection."

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَا مِنَ الأَنْبِيَاءِ مِنْ نَبِيٍّ إِلاَّ قَدْ أُعْطِيَ مِنَ الآيَاتِ مَا مِثْلُهُ آمَنَ عَلَيْهِ الْبَشَرُ وَإِنَّمَا كَانَ الَّذِي أُوتِيتُ وَحْيًا أَوْحَى اللَّهُ إِلَىَّ فَأَرْجُو أَنْ أَكُونَ أَكْثَرَهُمْ تَابِعًا يَوْمَ الْقِيَامَةِ ‏"‏ ‏.‏

It is narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) observed: There is not any prophet from among the prophets but that he was given miracles the like of which humans believed in it. But that which was given to me was only a revelation (the Holy Qur'an) of God, so I hope that I will have the greatest following on the Day of Resurrection.
