“Whoever wants to be cupped, let him seek out the seventeenth, nineteenth or twenty-first (of the month); and let none of you allow his blood to rage so that it kills him.”  

ابن ماجة:٣٤٨٦حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ حَدَّثَنَا عُثْمَانُ بْنُ مَطَرٍ عَنْ زَكَرِيَّا بْنِ مَيْسَرَةَ عَنِ النَّهَّاسِ بْنِ قَهْمٍ عَنْ أَنَسِ بْنِ مَالِكٍ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ أَرَادَ الْحِجَامَةَ فَلْيَتَحَرَّ سَبْعَةَ عَشَرَ أَوْ تِسْعَةَ عَشَرَ أَوْ إِحْدَى وَعِشْرِينَ وَلاَ يَتَبَيَّغْ بِأَحَدِكُمُ الدَّمُ فَيَقْتُلَهُ
