Sunan an-Nasa'i, Book 48, Hadith 115 (In-Book) ⓘ
Abu Shaikh narrated from his brother Himman: That when Mu'awiyah went on Hajj, he gathered together a group of the Companions of the Messenger of Allah [SAW] at the Ka'bah and said to them: "I adjure you by Allah, did the Messenger of Allah [SAW] forbid wearing gold?" They said: "Yes." He said: "And I bear witness to that."
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا عَبْدُ الصَّمَدِ، قَالَ حَدَّثَنَا حَرْبُ بْنُ شَدَّادٍ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنِي أَبُو شَيْخٍ، عَنْ أَخِيهِ، حِمَّانَ أَنَّ مُعَاوِيَةَ، عَامَ حَجَّ جَمَعَ نَفَرًا مِنْ أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي الْكَعْبَةِ فَقَالَ لَهُمْ أَنْشُدُكُمْ بِاللَّهِ هَلْ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ لُبُوسِ الذَّهَبِ قَالُوا نَعَمْ . قَالَ وَأَنَا أَشْهَدُ . خَالَفَهُ الأَوْزَاعِيُّ عَلَى اخْتِلاَفِ أَصْحَابِهِ عَلَيْهِ فِيهِ .
