Narrated Muawiya:
حَدَّثَنَا حِبَّانُ ، أَخْبَرَنَا عَبْدُ اللَّهِ ، عَنْ يُونُسَ ، عَنِ الزُّهْرِيِّ ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ ، أَنَّهُ سَمِعَ مُعَاوِيَةَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ، وَاللَّهُ الْمُعْطِي وَأَنَا الْقَاسِمُ، وَلاَ تَزَالُ هَذِهِ الأُمَّةُ ظَاهِرِينَ عَلَى مَنْ خَالَفَهُمْ حَتَّى يَأْتِيَ أَمْرُ اللَّهِ وَهُمْ ظَاهِرُونَ " .
Allah's Messenger (ﷺ) said, "If Allah wants to do good for somebody, he makes him comprehend the Religion (i.e. Islam), and Allah is the Giver and I am Al-Qasim (i.e. the distributor), and this (Muslim) nation will remain victorious over their opponents, till Allah's Order comes and they will still be victorious."
