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 isnad 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
