Sahih Muslim 1037d
It has been related by, Yazid b. al-Asamm that he heard Mu'awiya b. Abu Sfyan quote a tradition from Prophet ﷺ which he related from the Prophet (mail peace he upon him) -and he did not hear him quote from the Holy Prophet (masy peace be upon him) any tradition other than this in the course of his sermon from the pulpit-that whom Allah wants to do a favour, He grants him an understanding of religion. A group of people from the Muslims will remain on the Right Path and continue until the Day of Judgment to triumph over those who oppose them.
وَحَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا كَثِيرُ بْنُ هِشَامٍ، حَدَّثَنَا جَعْفَرٌ، - وَهُوَ ابْنُ بُرْقَانَ - حَدَّثَنَا يَزِيدُ بْنُ الأَصَمِّ، قَالَ سَمِعْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ، ذَكَرَ حَدِيثًا رَوَاهُ عَنِ النَّبِيِّ ﷺ لَمْ أَسْمَعْهُ رَوَى عَنِ النَّبِيِّ ﷺ عَلَى مِنْبَرِهِ حَدِيثًا غَيْرَهُ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ وَلاَ تَزَالُ عِصَابَةٌ مِنَ الْمُسْلِمِينَ يُقَاتِلُونَ عَلَى الْحَقِّ ظَاهِرِينَ عَلَى مَنْ نَاوَأَهُمْ إِلَى يَوْمِ الْقِيَامَةِ " .
