وَعَنْ عُمَرَ رَضِيَ اللَّهُ عَنْهُ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ لُبْسِ الْحَرِيرِ إِلَّا هَكَذَا وَرَفَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إصبعيه: الْوُسْطَى والسبابة وضمهما وَفِي رِوَايَةٍ لِمُسْلِمٍ: أَنَّهُ خَطَبَ بِالْجَابِيَةِ فَقَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ لُبْسِ الْحَرِيرِ إِلَّا مَوْضِعَ إِصْبَعَيْنِ أَوْ ثَلَاث أَو أَربع
Umar said the Prophet (sallallahu alayhi wa sallam) forbade wearing silk except to this extent, which was indicated by God’s messenger raising his middle and forefinger and joining them. (Bukhari and Muslim.) 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.
