Hadith 365
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنِ الشَّعْبِيِّ، عَنْ سُوَيْدِ بْنِ غَفَلَةَ، أَنَّ عُمَرَ، رَضِيَ اللَّهُ عَنْهُ خَطَبَ النَّاسَ بِالْجَابِيَةِ فَقَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ لُبْسِ الْحَرِيرِ إِلَّا مَوْضِعَ أُصْبُعَيْنِ أَوْ ثَلَاثَةٍ أَوْ أَرْبَعَةٍ وَأَشَارَ بِكَفِّهِ.
It was narrated from Suwaid bin Ghafalah that `Umar addressed the people in al-Jabiyah and said:
The Messenger of Allah (ﷺ) forbade wearing silk except the width of two fingers or three or four - and he gestured with his hand.
