 on the authority of the messenger of allah who said whoever is cupped on friday and dies he has a share in his blood. he also said cupping on sunday is a cure. he also said cupping on sunday is as if it were with the medicine of the sunnah.
وعن رسول الله أنه قال من احتجم يوم الجمعة فمات شرك في دمه . وقال الحجامة ليوم الأحد شفاء . وقال أيضا الحجامة يوم الأحد بدواء سنة .
