[Machine] I heard Muawiyah, who had a group of the Prophet's companions with him, say, "I swear by Allah, do you know that the Messenger of Allah ﷺ forbade wearing silk?" They said, "O Allah, yes."
سَمِعْتُ مُعَاوِيَةَ وَعِنْدَهُ رَهْطٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ فَقَالَ أَنْشُدُكُمْ بِاللهِ هَلْ تَعْلَمُونَ أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ لِبْسِ الْحَرِيرِ؟ قَالُوا اللهُمَّ نَعَمْ
When a group of the Companions of Muhammad [SAW] were with him: "Do you know that the Prophet of Allah [SAW] forbade wearing gold unless it was broken (into smaller pieces)?" They said: "By Allah, yes." (Using translation from Nasāʾī 5151)
أَنَّهُ سَمِعَ مُعَاوِيَةَ وَعِنْدَهُ جَمْعٌ مِنْ أَصْحَابِ مُحَمَّدٍ ﷺ فَقَالَ أَتَعْلَمُونَ أَنَّ نَبِيَّ اللهِ ﷺ نَهَى عَنْ لُبْسِ الْحَرِيرِ؟ قَالُوا اللهُمَّ نَعَمْ
