from Ḥimmān —
[Machine] Muawiyah performed Hajj and called a group of Ansar in the Kaaba, then he said, "I swear to Allah, didn't you hear the Messenger of Allah ﷺ forbid gold?" They said, "Yes, O Allah, we did." He said, "And I bear witness, didn't you hear that the Messenger of Allah ﷺ forbade the rows of leopards?" They said, "Yes, O Allah, we did." He said, "And I bear witness, didn't you hear that the Messenger of Allah ﷺ forbade silk?" They said, "Yes, O Allah, we did." He said, "And I bear witness."

عن حمان —
حَجَّ مُعَاوِيَةُ فَدَعَا نَفَرًا مِنَ الْأَنْصَارِ فِي الْكَعْبَةِ فَقَالَ «أَنْشُدُكُمُ اللهَ أَلَمْ تَسْمَعُوا رَسُولَ اللهِ ﷺ نَهَى عَنِ الذَّهَبِ؟» قَالُوا اللهُمَّ نَعَمْ قَالَ «وَأَنَا أَشْهَدُ أَلَمْ تَسْمَعُوا أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ صُفَفِ النُّمُورِ؟» قَالُوا نَعَمْ قَالَ «وَأَنَا أَشْهَدُ أَلَمْ تَسْمَعُوا أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنِ الْحَرِيرِ؟» قَالُوا اللهُمَّ نَعَمْ قَالَ «وَأَنَا أَشْهَدُ»
