2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْحُسَيْنِ بْنِ أَبِي الْعَلاءِ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الْحِجَامَةِ لِلصَّائِمِ قَالَ نَعَمْ إِذَا لَمْ يَخَفْ ضَعْفاً.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-Husayn ibn abu al-‘Ala’ who has said the following: “I once asked abu ‘Abd Allah , ‘Can a man apply cupping when he is fasting?’ He (the Imam) said, ‘Yes, if he is not afraid of weakness.’”
