He heard Muawiya, while a group of the Prophet's ﷺ companions were with him, say, "Do you know that the Prophet of Allah ﷺ forbade wearing gold except in small pieces?"They replied, "Yes."
أنه سمع معاوية- وعنده جمع من أصحاب النبي ﷺ-قال: أتعلمون أن نبي الله ﷺ نهى عن لبس الذهب إلا مقطعا؟ قالوا: نعم.
Nasai (5151) narrated it from Muhammad bin Muthanna, who said, Ibn Abu Adi narrated to us, from Saeed, from Qatada, from Abu Shaykh, that he heard Muawiya, and he mentioned it. Its chain of transmission is hasan because of Abu Shaykh Hinai, and it is said his name was Haywan, and he is hasan al-hadith. See its detailed sourcing in "The Prohibition of Riding the Leopard." The hadith has many other paths, among them what Nadr bin Shumayl narrated, saying, Bayhas bin Fahdan narrated to us, saying, Abu Shaykh Hinai narrated to us, and he mentioned it. Nasai (5159) narrated it. Nasai said, Ali bin Ghurab differed from him, narrating it from Bayhas, from Abu Shaykh, from Ibn Umar, who said, the Messenger of Allah ﷺ forbade wearing gold except in small pieces.Nasai said, the hadith of Nadr is closer to being correct. I say, it is as he said, for Ali bin Ghurab is daif. Abu Dawud declared him daif, and Ibn Hibban went to excess regarding him, saying, he narrated fabricated things, so relying on him as evidence is invalid. As for Nadr bin Shumayl, he is trustworthy and firmly reliable, among the narrators found in the six major collections.As for his statement "muqattaan," it means cut into pieces, that is, something small like a button, a tooth, or a nose ornament, unlike a large amount, which is forbidden because of the extravagance and vanity involved. And that was a time of jihad, so spending in the way of Allah was preferable to hoarding gold.
