سَهْلُ بْنُ زِيَادٍ عَنِ ابْنِ فَضَّالٍ عَمَّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ اللَّهِ (عليه السلام) قَالَ الْحِجَامَةُ فِي الرَّأْسِ هِيَ الْمُغِيثَةُ تَنْفَعُ مِنْ كُلِّ دَاءٍ إِلَّا السَّامَ وَ شَبَرَ مِنَ الْحَاجِبَيْنِ إِلَى حَيْثُ بَلَغَ إِبْهَامُهُ ثُمَّ قَالَ هَاهُنَا.
160. Sahl Bin Ziyad, from Ibn Fazzaal, from the one whom he mentioned, who has narrated the following: Abu Abdullah  having said: ‘The cupping in the head is beneficial from every illness except for the death, and ‘Shibr’ (the length of an extended palm) from both the eyebrows to where his thumb reaches’ (centre of the head). Then said: ‘Like here’.
