Mishkat al-Masabih, 4574, 4575

Ma'qil b. Yasar reported God’s messenger as saying:

“Cupping on Tuesday the 17th of the month is a cure for a year’s illness.” Harb b. Isma'il al-Kirmani, Ahmad’s companion, transmitted it, but his <i>isnad</i> is worthless. Thus it is stated in al-Muntaqa. Razin transmitted something to the same effect on the authority of Abu Huraira.

وَعَنْ مَعْقِلِ بْنِ يَسَارٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْحِجَامَةُ يَوْمُ الثُّلَاثَاءِ لِسَبْعَ عَشْرَةَ مِنَ الشَّهْرِ دَوَاءٌ لِدَاءِ السَّنَةِ» . رَوَاهُ حَرْبُ بْنُ إِسْمَاعِيلَ الْكِرْمَانِيُّ صَاحِبُ أَحْمَدَ وَلَيْسَ إِسْنَادُهُ بِذَاكَ هَكَذَا فِي الْمُنْتَقى وروى رزين نَحوه عَن أبي هُرَيْرَة
