'Amr b. Dinar reported from Wahb b. Munabbih:

I went to his house in San'a' and he offered me nuts grown in his house to eat. And his brother said: I heard Mu'awiya b. Abu Sufyan saying that he had heard the Messenger of Allah (ﷺ) as saying, and then he made a mention (of a hadith) like one mentioned above.

حَدَّثَنَا ابْنُ أَبِي عُمَرَ الْمَكِّيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرِو بْنِ دِينَارٍ، حَدَّثَنِي وَهْبُ بْنُ، مُنَبِّهٍ - وَدَخَلْتُ عَلَيْهِ فِي دَارِهِ بِصَنْعَاءَ فَأَطْعَمَنِي مِنْ جَوْزَةٍ فِي دَارِهِ - عَنْ أَخِيهِ قَالَ سَمِعْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏.‏ فَذَكَرَ مِثْلَهُ ‏.‏
