وَفِي رِوَايَةٍ لِمُسْلِمٍ: أَنَّهُ خَطَبَ بِالْجَابِيَةِ فَقَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ لُبْسِ الْحَرِيرِ إِلَّا مَوْضِعَ إِصْبَعَيْنِ أَوْ ثَلَاث أَو أَربع
A version by Muslim tells that in an address given by him at al-Jabiya (a town to the east of the Sea of Galilee, north of the Yarmuk battlefield. ‘Umar went there before the fall of Jerusalem.) he said God’s messenger forbade wearing silk except to the extent of two, three, or four fingers.
