The Book of Zakat
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ حَدَّثَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، قَالَ سَمِعْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ، وَهُوَ يَخْطُبُ يَقُولُ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ وَإِنَّمَا أَنَا قَاسِمٌ وَيُعْطِي اللَّهُ " .Abd al-Rahman b. Auf reported:I heard Mu'awiya b. Abu Sufyan saying in an address that he had heard the Messenger of Allah (ﷺ) as saying: He to whom Allah intends to do good, He gives him insight into religion. And I am only the distributor while Allah is the Bestower
