Hadith
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.
