Arabic hadith text
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 ‏"
Translation
Narrated Abu Huraira

The Prophet (ﷺ) said, "Every Prophet was given miracles because of which people believed, but what I have been given, is 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."
