وَعَنْ أَبِي هُرَيْرَةَ عَنْ
رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنِ احْتَجَمَ لِسَبْعَ عَشْرَةَ وَتِسْعَ عَشْرَةَ وَإِحْدَى وَعِشْرِينَ كَانَ شِفَاءً لَهُ مِنْ كُلِّ دَاء»
Abu Hurayrah reported God’s messenger as saying, “If anyone has himself cupped on the 17th, 19th, and 21st, it will be a remedy for every disease.”
