عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ رَجُلٍ مِنَ الْكُوفِيِّينَ عَنْ أَبِي عُرْوَةَ أَخِي شُعَيْبٍ أَوْ عَنْ شُعَيْبٍ الْعَقَرْقُوفِيِّ قَالَ دَخَلْتُ عَلَى أَبِي الْحَسَنِ الْأَوَّلِ (عليه السلام) وَ هُوَ يَحْتَجِمُ يَوْمَ الْأَرْبِعَاءِ فِي الْحَبْسِ فَقُلْتُ لَهُ إِنَّ هَذَا يَوْمٌ يَقُولُ النَّاسُ إِنَّ مَنِ احْتَجَمَ فِيهِ أَصَابَهُ الْبَرَصُ فَقَالَ إِنَّمَا يُخَافُ ذَلِكَ عَلَى مَنْ حَمَلَتْهُ أُمُّهُ فِي حَيْضِهَا.
224. A number from our companions, from Sahl Bin Ziyad, from Yaqoub Bin Yazeed, from a man from the people of Al-Kufa, from Abu Urwa the brother of Shuayb, or from Shuayb Al-Aqarqufy who said: I came up to Abu Al-Hassan  the First  whilst he  was doing the cupping (Al-Hajaamat) on the day of Wednesday in the prison. So I said to him , ‘This is the day for which the people say that the one who gets cupping (Al-Hajaamat) done would be struck by vitiligo (white patches on the body)’. He  said: ‘But rather, the one who fears that is the one whose mother conceived him during her menstruation (Walud-ul-Haiz, the one would always be the enemy of Alye Mohammed )’.
